FVS338 ProSafe VPN Firewall 50 Reference Manual

Configuring Multi-Home LAN IPs

If you have computers that are using different IP address ranges in the LAN (for example,

172.16.2.0or 10.0.0.0), then you can add “aliases” to the LAN port which give computers on those networks access to the Internet. This allows the firewall to act as a gateway to additional logical subnets on your LAN.

To add a secondary LAN IP address:

1.Select Network Configuration from the main menu and LAN Setup from the secondary menu. Click the Multi Home LAN IPs Setup link (see Figure 3-2 on page 3-4) The Secondary LAN IP Setup screen will display.

2.Enter the Secondary IP address and Subnet Mask and click Add. The Secondary IP address will be added to the Available Secondary LAN IPs table.

Note: Additional IP addresses cannot be configured in the DHCP server. The hosts on the secondary subnets must be manually configured with IP addresses, gateway IP and DNS server IP addresses.

Figure 3-2

Tip: The Secondary LAN IP address will be assigned to the LAN interface of the router and can be used as a gateway by the secondary subnet.
