Secondary LAN IP Setup
If you have computers using different IP networks in the LAN, (for example:
172.16.2.0, 10.0.0.0), then you can add "aliases" to the LAN port and give
computers on those networks, access to the Internet.
Available Secondary LAN IPs
The tables lists the secondary LAN IP addresses added to the router.
IP Address: The IP address alias added to the LAN port of the router. This is the
gateway for computers that need to access the Internet.
Subnet Mask: IPv4 Subnet Mask.
Action/Edit: Click to make changes to the selected entry.
Select All: Selects all the entries in the Available Secondary LAN IPs table.
Delete: Deletes selected entries from the Available Secondary LAN IPs table.
Add Secondary LAN IP Address
To add a secondary LAN IP address, type in the IP Address and the Subnet
Mask in the respective text fields and click Add.
Note: Additional IP addresses cannot be configured in the DHCP server. The
hosts on the secondary subnets must be manually configured with the IP
addresses, gateway IP and DNS server IPs.
IMPORTANT!
Make sure the secondary IP addresses are different from the LAN, WAN, and
any other subnet attached to this router.
Example:
ADSL IP address: 10.0.0.1 with subnet 255.0.0.0
WAN Ethernet IP address: 20.0.0.1 with subnet 255.0.0.0
LAN IP address: 192.168.1.1 with subnet 255.255.255.0
Secondary LAN IP: 192.168.20.1 with subnet 255.255.255.0
