• Delete. Deletes the binding or bindings.

Configure Secondary WAN Addresses

You can set up a single WAN port to be accessed through multiple IP addresses by adding
aliases to the port. An alias is a secondary WAN address. One advantage is, for example,
that you can assign different virtual IP addresses to a web server and an FTP server, even
though both servers use the same physical IP address. You can add several secondary IP
addresses to a single WAN port.
After you have configured secondary WAN addresses, these addresses are displayed on the
following firewall rule screens:
• In the WAN Destination IP Address drop-down lists of the following inbound firewall rule
screens:
- Add LAN WAN Inbound Service screen
- Add DMZ WAN Inbound Service screen
• In the NAT IP drop-down lists of the following outbound firewall rule screens:
- Add LAN WAN Outbound Service screen
- Add DMZ WAN Outbound Service screen
For more information about firewall rules, see
Traffic on page 121).
It is important that you ensure that any secondary WAN addresses are different from the
primary WAN, LAN, and DMZ IP addresses that are already configured on the UTM.
However, primary and secondary WAN addresses can be in the same subnet. The following
is an example of correctly configured IP addresses on a multiple WAN port model:
• Primary WAN1 IP address. 10.121.0.1 with subnet 255.255.255.0
• Secondary WAN1 IP address. 10.121.26.1 with subnet 255.255.255.0
• Primary WAN2 IP address. 10.216.75.1 with subnet 255.255.255.0
• Secondary WAN2 IP address. 10.216.82.1 with subnet 255.255.255.0
• 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. 192.168.2.1 with subnet 255.255.255.0

To add a secondary WAN address to a WAN interface:
1. Select Network Config > WAN Settings. The WAN screen displays (see
page 67).
2. Click the Edit button in the Action column of the WAN interface for which you want to add a
secondary address. The WAN ISP Settings screen displays (see
which shows the WAN1 ISP Settings screen as an example).
