SmartShare® User Manual  
Installation Guide  
1. Connect to the local network equipment  
Connect the LAN port on the SmartShare to any Ethernet port on the local network  
switch, using a straight Ethernet patch cable.  
2. Start the setup menu  
Use a web browser on a PC connected to the local network to start the setup menu in  
the SmartShare.  
The setup menu address is: http://192.168.2.1/  
The factory default administrator user name is: adminand password: admin  
3. Configure the Internet connection  
Go to the WAN page and configure the Internet connection and enter the download  
and upload speeds in Kbit/s.  
The information that must be entered on the WAN page must be obtained from the  
Internet service provider (ISP). The ISP usually supplies this information in a letter  
accompanying the confirmation of the Internet subscription.  
Please note that the connection speed advertised by most Internet service providers  
are the gross speeds, while the settings in the SmartShare must be entered as the net  
speeds, which means that the settings may need some adjustment to compensate for  
the difference.  
Entering the speeds as 80% of the ISP’s advertised speeds is a good rule of thumb.  
Go to the Save page to save and activate the new settings.  
4. Connect to the Internet equipment  
Connect the WAN port on the SmartShare to the Ethernet LAN port on the Internet  
modem, using a straight Ethernet patch cable.  
5. Test the configured Internet connection speed  
Test that the download speed settings are correct by downloading from a very fast  
server on the Internet from two PCs simultaneously. Go to the Status page and check  
that the Download Limiter status changes from READY to ACTIVE while the  
download connection is saturated. If it does not change, try decreasing the download  
speed entered on the WAN page by 10-30%. Keep testing and decreasing the values  
until satisfied.  
Test that the upload speed settings are correct by uploading to a very fast server on the  
Internet from two PCs simultaneously, while monitoring the Upload Limiter status.

SmartShare® User Manual  
The SmartShare Bandwidth Management System  
This section describes the SmartShare bandwidth management system in details, and  
is written for network experts only.  
User Load Balancing  
Conventional routers simply forward all packets to/from users in the same order the  
packets arrive at the router, so the users with a lot of packets get a larger share of the  
available bandwidth than the users with fewer packets.  
The SmartShare User Load Balancer intelligently forwards packets to/from individual  
users in turn, so every user gets a reasonable share of the available bandwidth.  
User Identification  
The SmartShare identifies individual users by their IP address presented to the LAN  
interface on the SmartShare. This also means that if a group of users in an apartment  
shares the apartment’s network connection through another NAT router in the  
apartment, they will be treated as one single user, because that NAT router only  
presents one IP address to the SmartShare.  
The IP address range controlled by the SmartShare is visible on the LAN  
configuration menu. Each IP address in this range is considered an individual user.  
Advanced administrators can use the Bandwidth User Groups to specify which IP  
address ranges are controlled by the SmartShare. When specifying an address range,  
you have the option of choosing to identify all IP addresses from a /24 subnet as one  
user.  
Overflow Users  
All IP addresses outside the controlled address range are considered overflow users,  
and will be crammed together and treated as a single virtual user by the SmartShare.  
This means that the overflow users can access the Internet, but the entire group of  
overflow users will only get the bandwidth of one single user.  
There is no bandwidth distribution within the group of overflow users. A single heavy  
user in the group of overflow users can consume all the bandwidth assigned to the  
group of overflow users, and thus block the connection for the other overflow users.  
Download and Upload Limiters  
The SmartShare monitors the download and upload bandwidth, and while there is  
bandwidth enough, all users can use all the bandwidth they like.  
When the download bandwidth becomes overloaded, the SmartShare starts restricting  
the heavy users by activating the Download Limiter.  
When the upload bandwidth becomes overloaded, the SmartShare starts restricting the  
heavy users by activating the Upload Limiter.  
The SmartShare Download and Upload Limiters are designed to ensure that no single  
user is limited more than appropriate.  
Advanced administrators can use the Bandwidth User Groups to specify maximum  
download and upload bandwidth per user in each group of users.

SmartShare® User Manual  
Dynamic Quality of Service  
The SmartShare always prioritizes timing critical traffic flows, such as IP telephony  
and online gaming, over ordinary traffic flows.  
The priority assignment is based on traffic pattern analysis of each flow. It is not  
based on the TCP/UDP port number, TOS precedence, DSCP or other fields set in the  
packet, because those properties can be controlled by peer-to-peer applications or  
malicious users.  
Dynamic QOS is an integral part of the SmartShare bandwidth management system,  
so it does not require any configuration or allocation of bandwidth.  
The SmartShare typically recognizes a timing critical flow and assigns it highest  
priority within one second.  
Flow Management  
All NAT routers contain a table, where each flow is registered while established. Each  
entry in the flow table contains the public IP addresses and TCP/UDP port numbers of  
the flow and the corresponding IP address and TCP/UDP port number of the computer  
on the LAN. The same principle applies to the NAT router in the SmartShare.  
The SmartShare flow table is large enough to handle the many flows that can be  
expected when many users are active. In addition to having a very large flow table,  
the SmartShare Flow Manager is designed to handle excessive flows without crashing  
or freezing.  
Just like the SmartShare Download and Upload Limiters prevent heavy users from  
eating up all the available Internet bandwidth at the expense of other users, the  
SmartShare Flow Manager prevents heavy users from eating up all the available flows  
in the flow table at the expense of other users.  
LowLatency Network Overclocking®  
As the name suggests, any Network Overclocking® may have unwanted side effects,  
and should be disabled if it causes problems.  
When LowLatency is enabled, the TCP MTU is lowered significantly, and thus the  
packets become smaller. When the packets are smaller, the packet rate is increased,  
and thus the delay and jitter is decreased.  
Obviously, using smaller packets means that more packets must be used to convey the  
same amount of data, so it does not increase the effective bandwidth.  
Modifying the TCP MTU is known from PPPoE connections, where the MTU is  
lowered slightly to make room for the PPPoE header added to the packets.

SmartShare® User Manual  
Status menu  
This page shows the current status of the Internet connection.  
System  
This shows system status, such as the name, location and contact information, current  
time (if an NTP server is available), the duration since the last time the SmartShare  
was powered on or rebooted, and the memory utilization.  
WAN  
This shows the status of logical connection to the ISP, regardless of the physical  
connection’s link status.  
If the WAN is configured to use a Static IP address, the status will always show the  
link as being up, because the SmartShare can not know if the ISP will respond to  
traffic or not.  
When the WAN has received its configuration from the ISP, the status will show the  
link as being up and the assigned IP Address will be visible.  
The permanent MAC address of the WAN is visible, because some ISP’s ask for the  
MAC address when they set up their customer’s access.  
Bandwidth Usage  
Download and Upload Rates  
The download and upload rates show the current bandwidth utilization in Kbit/s.  
Flow Rate  
The flow rate shows the number of new flows established per second.  
Bytes Downloaded and Uploaded  
This shows the total number of bytes transferred in each direction.  
Flows Processed  
This shows the total number of flows processed, including currently established flows.  
Bandwidth Manager  
Concurrent Flows  
When analyzing the utilization of the Internet connection, it is not only interesting to  
know the bandwidth utilization, but also how many concurrent flows are established,  
because each flow uses memory in the SmartShare. Flows are sometimes called  
sessions or connections. A high number of concurrent flows means that the computers  
on the local net are connected to many servers on the Internet, but it does not  
necessarily mean that packets are flowing and bandwidth is being used.  
Download Limiter  
The SmartShare monitors the download bandwidth, and while there is bandwidth  
enough, all users can use all the bandwidth they like. In this situation, the Download  
Limiter status is shown as READY.

SmartShare® User Manual  
When the download bandwidth becomes overloaded, the SmartShare starts restricting  
the heavy users by activating the Download Limiter. In this situation, the Download  
Limiter status is shown as ACTIVE.  
Upload Limiter  
The SmartShare monitors the upload bandwidth, and while there is bandwidth  
enough, all users can use all the bandwidth they like. In this situation, the Upload  
Limiter status is shown as READY.  
When the upload bandwidth becomes overloaded, the SmartShare starts restricting the  
heavy users by activating the Upload Limiter. In this situation, the Upload Limiter  
status is shown as ACTIVE.  
Anti Terror Logger  
Log Servers  
This shows the overall status of the FTP servers where the SmartShare stores the ATL  
log files. The status can be: Initializing, OK, Warning or Error.  
SNMP Agents  
This shows the overall status of the SNMP agents in the switches and routers on the  
local network. The status can be: Initializing, OK or Error.  
Buffer Usage  
The SmartShare temporarily stores the ATL log files in a buffer until they are  
transferred to the FTP server. Buffer Usage shows the utilization of this buffer.  
Flows Logged  
Shows how many flows have been logged by the SmartShare since the last time the  
SmartShare was powered on or rebooted.

SmartShare® User Manual  
Internet/WAN (Wide Area Network) configuration menu  
The Internet service provider usually supplies all the information that is needed to set  
the WAN configuration in a letter accompanying the confirmation of the Internet  
subscription.  
Internet Service Provider connection type  
The WAN can be configured for 3 types of connection to the Internet service  
provider:  
Static IP  
DHCP  
PPPoE  
WAN with Static IP  
The following information is required:  
IP address  
Netmask  
Router (Default Gateway)  
Primary DNS Server  
The following information is optional:  
Secondary DNS Server  
WAN with DHCP  
This type of connection is fully automatic. If the Internet service provider (ISP)  
requires a device name in the DHCP request, it can be configured here.  
WAN with PPPoE  
The following information is required:  
PPPoE username  
PPPoE password  
Connection Speed  
The Internet connection speed must be set correctly, or the bandwidth distribution will  
not function as intended.  
The following information is required:  
Download speed in Kbit/s  
Upload speed in Kbit/s  
If the connection speed advertised by the Internet service provider (ISP) contains two  
numbers, for example 1024/256; the download speed is normally the larger of the  
numbers and the upload speed is the lesser.  
Please note that an advertised speed of 1M sometimes means 1024 and 2M sometimes  
means 2048, but 10M typically means 10000 and 100M always means 100000.  
Many ISPs advertise the gross connection speed, which does not include overhead in  
the ISP’s network (e.g. PPPoE encapsulation and ATM cell alignment). The speed  
settings in the SmartShare must be entered as net values. This means that they may  
need some adjustment to compensate for the overhead in ISP’s network. Entering the  
speeds as 80% of the ISP’s advertised speeds is a good rule of thumb.

ATL (Anti Terror Logger) configuration menu  
Log File Storage  
The SmartShare stores the ATL log files on an external FTP server.  
If ATL is enabled, it is possible to configure up to two FTP servers for storing the  
ATL log files. When the SmartShare is ready to store an ATL log file, it will use the  
primary FTP server. Every time the primary FTP server fails to receive an ATL log  
file, the SmartShare will store it on the secondary FTP server instead.  
FTP Server, User Name and Password are required fields, Directory Path is optional.  
The Status field shows the result of the last FTP transfer.  
Local Network SNMP Agents  
The SmartShare uses the SNMP agents in the switches and routers on the local  
network to locate where each MAC address and IP address is connected, and thus  
identifies the users.  
If ATL is enabled, it is possible to configure which SNMP agents are present on the  
local network. Information about each switch and router on the LAN should be set, so  
the SmartShare is able to poll them for the required information to identify the users.  
IP Address and Community are required fields. The Status field shows the result of  
the last SNMP poll of the device.

LowLatency Network Overclocking  
Enabling LowLatency Network Overclocking has the following effects:  
The “ping time” in online games is lowered.  
The delay and jitter for IP telephony is minimized.  
LowLatency Network Overclocking works by reducing the TCP MTU significantly,  
and may not be compatible with all web sites and Internet services. If it causes  
problems, it can be disabled again.  
The default setting for LowLatency Network Overclocking is: Disabled  
DHCP Proxy  
If a DHCP server is not connected to the layer 2 LAN, and the built-in DHCP server  
is disabled, the DHCP proxy can be used to relay DHCP requests from DHCP clients  
on the LAN to remote DHCP servers via layer 3.  
The default configuration is: Disabled

SmartShare® User Manual  
Outgoing SMTP Connections  
The SmartShare has 4 different modes for handling outgoing SMTP (TCP port 25)  
connections from the local network to the WAN:  
Allow All.  
Allow to External Server only.  
Redirect all to External Server.  
Allow from Local Mail Servers only.  
The default configuration is: Allow All  
Allow All  
Allow all local users to connect to any SMTP server on the WAN.  
Allow to External Server only  
Allow all local users to connect to the specified SMTP server on the WAN only.  
Attempts to connect to other SMTP servers on the WAN will be rejected by the  
SmartShare.  
Redirect all to External Server  
Redirect all outgoing SMTP connections to the specified SMTP server on the WAN.  
In this mode, the packet headers of all outgoing SMTP connections are modified, so  
the connection is established to the specified SMTP server instead.  
This mode is useful if the local users are only allowed to use a specific SMTP server,  
but are unable or unwilling to configure their email applications.  
Allow from Local Mail Servers only  
Allow the specified local mail servers to connect to any SMTP server on the WAN,  
and reject attempts from all other local users to connect to SMTP servers on the  
WAN.  
System Information  
System contact and location can be configured. This is not used by the system itself. It  
is shown on the status web page and available via SNMP.

SmartShare® User Manual  
Bandwidth User Groups  
Bandwidth User Groups can be used to configure which IP address ranges the  
bandwidth manager controls, and optionally set per-user bandwidth limits within each  
user group.  
The following can be configured for each user group:  
First and last IP address.  
User type. Choose “IP Address” for normal user identification, where each IP  
address identifies one user. Choose “/24 Subnet” if you want all IP addresses  
within a /24 subnet to be identified as one single user. This can be used in  
routed networks, where each apartment (or office) is assigned a /24 subnet.  
Download and Upload bandwidth per user (optional). This can be used to set  
the per-user maximum bandwidth allowed for users in the user group. If left  
blank, there will be no specific bandwidth limits; the users will participate  
normally in the smart management of all the available bandwidth.  
Description. This can be used to store an informative description of the user  
group.  
The default configuration is: Disabled  
Additional LAN Subnets  
Routes in addition to the LAN subnet can be added here. Each route added can be a  
NAT or a transparent route.  
In a switched network with NAT to the LAN, some users on the LAN can have public  
IP addresses by adding them to this table as follows: Set Subnet to the user’s public IP  
address, set Subnet Mask to 255.255.255.255, leave Next Hop Gateway empty and  
select IP Routing.  
On the user’s PC, set the IP address to the public IP address and the Subnet Mask to  
255.255.255.255 (or 255.255.255.252 if 255.255.255.255 is not accepted) and Default  
Gateway to the IP address of the SmartShare, as shown on the LAN configuration  
menu (e.g. 192.168.2.1).  
Remember to configure the Bandwidth Distributor with the added public IP addresses.  
The default configuration is: Disabled

SmartShare® User Manual  
Security Considerations  
Physical Access  
The SmartShare should be installed in a locked patch panel. Anyone with physical  
access to the SmartShare can power it off, disconnect it or change the configuration  
via the Serial port.  
Password Protection  
The SmartShare configuration menu is password protected. Keep your password safe.  
Firewall  
The SmartShare firewall prevents potential intruders on the Internet from accessing  
computers on the local network.  
The firewall does not prevent users on the local network from downloading virus or  
other malware from the Internet to their computers. Users on the local network should  
protect their computers with anti-virus software.  
The firewall does not prevent intruders connected on the local network from accessing  
other computers on the local network. Switches and wireless access points in the local  
network should prevent intruders and other users on the local network from accessing  
each other’s computers. For further information, please refer to the chapter about  
protecting local users from each other.  
Protecting Local Users from Each Other  
When installing and configuring the local network infrastructure, i.e. switches and  
wireless access points, it should be considered if the local network should be open  
(where all local users can connect to each other and share files etc.) or protected  
(where all local users are separated from each other, and each user only has access to  
the Internet and local servers).  
User separation has different names, depending on equipment and vendor. In  
switches, look for “source-port filters” (HP ProCurve terminology), “Private VLANs”  
(Cisco terminology) or similar. In wireless access points, look for “AP isolation”,  
“client isolation” or similar.  
User separation does not affect the SmartShare, and the SmartShare works equally  
well with both open and protected networks.  
Troubleshooting and FAQ  
Q: After the SmartShare was installed, some of the computers on the local network  
can no longer access the Internet.  
A: This is probably because the computers still have the old configuration from the  
previous Internet router. In Microsoft Windows, start a Command Prompt (Start ->  
Run; cmd.exe), and run the command ipconfig /releaseand then run the  
command ipconfig /renew.  
Q: There is no connectivity from the LAN to the WAN after the LAN has been  
configured on the SmartShare.  
A: The LAN can not use the same IP address range as the WAN. Verify that the  
configuration doesn’t conflict.

Q: After powering on the SmartShare, the WAN connection to the ISP is not  
established.  
A: First, verify that everything is correctly connected. It may take a few minutes for  
the WAN connection to the ISP to stabilize; if it isn’t established after a few minutes,  
verify that the configuration in the WAN menu is correct. If it still doesn’t work,  
disconnect the SmartShare and use a laptop to verify that the connection from the ISP  
works.  
Q: Users with peer-to-peer applications have problems accessing the Internet.  
A: Configure the peer-to-peer application to use fewer simultaneous flows (a.k.a.  
connections or sessions).  
Q: The administrator password for the SmartShare is lost.  
A: Use the Serial port to enable the default username and password for 5 minutes,  
then login via the web and set a new password. Refer to “Using the Serial Port”.  
Q: The SmartShare can not be accessed any more.  
A: Use the Serial port to restore the factory default settings. Refer to “Using the Serial  
Port”.  
Q: Some of the computers on the local network can not access the Internet.  
A: If a device with a DHCP server is wrongly connected to the LAN, the computers  
on the LAN may get an incorrect configuration from the unauthorized DHCP server.  
Most routers and wireless access points have a DHCP server on their LAN ports. Run  
the command ipconfigon a computer having access problems. If it shows an IP  
address outside the range configured in the SmartShare built-in DHCP server, a  
device with a DHCP server is wrongly connected to the LAN. Locate the device and  
disconnect it from the LAN.  
Q: A user needs a public IP address, but the SmartShare is in NAT Routing mode.  
A: Public IP addresses can be added using the “Additional LAN Subnets” feature.  
Q: The SmartShare has blocked access for a peer-to-peer user.  
A: The SmartShare does not block access for peer-to-peer users. However, the peer-  
to-peer user may have exceeded the number of allowed concurrent flows accepted by  
the SmartShare Flow Manager, and it has determined to start limiting the number of  
flows for this user, in order to protect the other users. Ask the peer-to-peer user to  
wait for three hours until the flows have been released.

The consumption at the primary side of the power supply, i.e. at the 110-240V plug, is  
shown in the table above. The annual cost of electricity for the SmartShare can be  
estimated by multiplying the price of electricity (per kWh) with the typical annual  
power consumption of the installed SmartShare model.
