Configuring Multi-Home LAN IPs Addresses
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 through the VPN firewall. This allows the VPN firewall to act as a gateway to
additional logical subnets on your LAN. You can assign the VPN firewall an IP address on each
additional logical subnet.
To add a secondary LAN IP address:
1. Select Network Configuration from the primary menu and LAN Settings from the submenu.
The LAN Setup screen will display.
2. Click the LAN Multi-homing tab. The LAN Multi-homing screen will display.
The Available Secondary LAN IPs table lists the secondary LAN IP addresses added to the
VPN firewall.
• IP Address. The IP address alias added to the LAN port of the VPN firewall. 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.
Note: The reserved address will not be assigned until the next time the PC contacts the
VPN firewall's DHCP server. Reboot the PC or access its IP configuration and
force a DHCP release and renew.
