ZyWALL USG 1000 Support Notes
To make this scenario works the follow the configuration steps as stated below:
1) Login the ZyWALL USG GUI and setup the ge2 interface for internet connection and
manually assign a static IP. The configuration path is ZyWALL USG > Configuration >
Network > Interface > Edit > ge2
Please use this same method to assign IP for the LAN and DMZ interface.
2) Switch to Configuration > Network > Interface > Bridge, add a new Bridge Interface.
First we enable this interface and give it a name, place the available ports into the member
ports and make them become the member of this bridge interface. Moreover, don't forget to
set the WAN IP information here since it is a "Bridge mode & Router (NAT) mode co-exist"
example and the NAT mode will need it. Here the bridge mode looks most likely a routing
bridge mode instead of the pure bridge mode. Thus, it needs an IP address. You may use the
same IP address that it used in the WAN interface, however you will get a warning message
like below.
If you got more than one IP, you can pick the other one here.
