Configuring Multi Home LAN IPs
If you have computers o n you r LAN u si ng differen t IP address ranges (for example, 172.16.2.0 or
10.0.0.0), then you can add “aliases” to the LAN port thereby giving computers on those networks
access to the Internet. This allows the firewall to act as a gateway to additional logical subnets on
your LAN. You can assign the firewall an IP address on each additional logical subnet
•The Av ailable Secondary LAN IPs table lists the secondary LAN IP addresses added to the
router.
•The IP Addr ess is the “alias” added to the LAN port of the router. This will be the gateway for
computers that need to access the Internet.
•The Subnet Mask is the IPv4 Subnet Mask.
To add a secondary LAN IP address:
1. Enter the IP Address and the Subnet Mask in the respective fields of the Add Secondary LAN
IP Address section.
2. Click Add. The new Secondary LAN IP address will appear in the Availa ble Secondary LAN
IPs table.
3. Click Select all to select all the entries in the Available Secondary LAN IPs table. All the
radio buttons are selected.
