3.4.1 LAN Settings
The network settings for the router.
Network Settings allows you to change the default IP address for your router.
However, in most cases you do not need to change this setting.
Note: The IP address for the router is used on your private network only. It is not possible to
change the subnet mask.
Click on Save LAN Settings and then Restart for the changes to take effect.
3.4.2 DHCP
DHCP Server allows you to enable or disable the built-in DHCP server.
When enabled, all clients on your private network will automatically obtain an IP address from the
range specified under Client IP Address Range (valid range is from 1 to 254). When disabled you
have to manually enter an IP address from this range into each client.
Client Network Information allows you to set a domain name for the router and specify an
additional DNS server.
Static Address Assignment: Can be used when you want a client to obtain the same IP address
each time it logs on to your private network. This setting works no matter if the DHCP Server is
enabled or disabled. Select how you want to identify the client, either by hostname or MAC address
(it is possible to define 253 static IP addresses based on MAC addresses or hostnames).Type in
the hostname or the MAC address under Host Identifier and finally, set the desired IP address
under Internal Address.
Please make sure not to assign the IP address of the router to any of the clients.
Click on Add and then Save DHCP Settings when you are finished.
View DHCP Table: is a function that shows the IP and MAC addresses of all clients that are
connected to the router.
Click on Save DHCP Settings and then Restart for the changes to take effect.
3.4.3 Port Forwarding
The settings for manually unblocking certain communication ports in your private network.
Reserved Ports is a list of logical ports that cannot be used to access your private network from the
public Internet.
Port Forwarding to LAN lets you specify which ports clients on the public Internet shall be able to
communicate through, to clients on your private network.
Under Port Range, select a range (any range that does not contain the ports listed under Reserved
Ports) from 0-65535. Select the type of traffic that should be let through on these ports, TCP or
UDP, or Both. Finally, type in the Destination Address, which is the IP address of the client on your
private network that you want to be accessible from the public Internet.
It is also possible to forward incoming GRE (Generic Routing Encapsulation) traffic to a single host.
Click on Add when you are finished.
Note: By default, no traffic is permitted inwards if the request is initiated by an external user.
However, clients on your private network can always access the public Internet.
Click on Restart for the changes to take effect.
3.4.4 UPnP
The settings for Universal Plug and Play.
The router supports Universal Plug and Play. UPnP is a feature that enables client application on
devices behind the router to automatically trigger the opening of TCP/UDP ports through the
firewall in the router.
As a security precaution, this feature is disabled by default and can be enabled manually.
