The SmartShare® is an integrated bandwidth manager and NAT router with builtin DHCP server and optional anti terror logger. The SmartShare can supplement an
existing Internet router or replace a traditional NAT router.
Key Features
Bandwidth Manager with User Load Balancing and Dynamic QOS. The patent
pending SmartShare bandwidth management technology automatically monitors and
manages the Internet connection, so every active user on the local network gets a fair
amount of the shared Internet bandwidth, and ensures that the Internet connection
always is available for all users on the local network. It also optimizes the use of
bandwidth, so the Internet connection can be fully utilized, regardless of the number
of active users – if only one user is active, that one user gets all the bandwidth. The
Dynamic Quality of Service (Dynamic QOS) technology ensures that IP telephony
and online gaming is not affected by other applications.
NAT Router with Individual IP Routing, SPI Firewall and Port Forwarding. The
network address translation (NAT) technology makes it possible for multiple PCs to
share a single Internet IP address, by translating the individual IP addresses of each
PC on the local network to the shared IP address and keeping track of each
translation, thereby maintaining the connection from each PC on the local network to
the Internet. Combined with individual IP routing, dedicated PCs on the local network
can use public IP addresses, thus bypassing the NAT. The stateful packet inspection
(SPI) firewall ensures that no PC outside the local network can establish a connection
to any PC on the local network, and thus protects the PCs on the local network from
intruders coming from the Internet. With port forwarding, specific servers on the local
network can be accessed from the Internet, so e.g. a public web server can be set up
on the local network.
DHCP Server. The DHCP server technology automatically assigns the required
network information to the PCs on the local network. This means that the users do not
have to worry about configuring their PCs with the correct IP address, netmask,
gateway and DNS servers.
Anti Terror Logger (firmware option). The anti terror logger (ATL) technology
collects and records information about Internet traffic flows of individual users as
required by EU and Danish legislation.
Developed in Denmark.
Made in Taiwan.

Patents pending. SmartShare® and Network Overclocking® are registered trademarks.
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: admin and 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.
