Configuring Multi Home LAN IP Addresses
If you have computers on your LAN using different IP address ranges (for example,
172.16.2.0 or 10.0.0.0), you can add “aliases” to the LAN port, giving 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 > LAN Settings from the menu, and click the LAN
Multi-homing tab. The LAN Multi-homing screen is displayed.
The Available Secondary LAN IPs table lists the secondary LAN IP addresses added to
the VPN firewall.
IP Address. The “alias,” an additional IP address hosted by the LAN port of the VPN
firewall. This address will be the gateway for computers on the secondary subnet.
Subnet Mask. The IPv4 subnet mask that defines the range of the secondary subnet.
2. In the Add Secondary LAN IP Address section, enter the additional IP address and
subnet mask to be assigned to the LAN port of the VPN firewall.
3. Click Add. The new Secondary LAN IP address will appear in the Available Secondary
LAN IPs table.
Note: IP addresses on these secondary subnets cannot be configured in
the DHCP server. The hosts on the secondary subnets must be
manually configured with IP addresses, gateway IP addresses, and
DNS server IP addresses.
Tip: The secondary LAN IP address will be assigned to the LAN interface of
the VPN firewall and can be used as a gateway by computers on the
secondary subnet.
