Configuring Multi-Home LAN IPs on the Default VLAN

If you have computers using different IP networks in the LAN, (for example, 172.16.2.0 or 10.0.0.0), you can add aliases to the LAN ports and give computers on those networks access to the Internet, but you can do so only for the default VLAN. The IP address that is assigned as a secondary IP address must be unique and must not be assigned to the VLAN.

It is important that you ensure that any secondary LAN addresses are different from the primary LAN, WAN, and DMZ IP addresses and subnet addresses that are already configured on the UTM. The following is an example of properly configured IP addresses on a dual-WAN port model:

WAN1 IP address: 10.0.0.1 with subnet 255.0.0.0

WAN2 IP address: 20.0.0.1 with subnet 255.0.0.0

DMZ IP address: 192.168.10.1 with subnet 255.255.255.0

Primary LAN IP address: 192.168.1.1 with subnet 255.255.255.0

Secondary LAN IP address: 192.168.20.1 with subnet 255.255.255.0

To add a secondary LAN IP address:

1.Select Network Config > LAN Settings from the menu. The LAN Settings submenu tabs appear, with the LAN Setup screen in view.

2.Click the LAN Multi-homingsubmenu tab. The LAN Multi-homing screen displays.
