15.1.17 NAT Routing Command Example

Syntax:

ip nat routing [0:LAN1:DMZ2:WLAN] [0:no1:yes]

Use this command to set the ZyWALL to route traffic that does not match a NAT rule through a specific interface. An example of when you may want to use this is if you have servers with public IP addresses connected to the LAN, DMZ or WLAN. By default the ZyWALL routes traffic that does not match a NAT rule out through the DMZ interface.

The following command example sets the ZyWALL to route traffic that does not match a NAT rule through the WLAN interface.

ras> ip nat routing 2 1

Routing can work in NAT when no NAT rule match.

LAN: no

DMZ: yes WLAN: yes
