Creating a WAN bridge allows users with multiple public IP addresses to use an internal port (LAN1, LAN2, DMZ), to bypass NAT and have public access (with public IP). To set up the bridge for the WAN connection, start by setting the WAN connection you will be bridging to obtain an IP address automatically (or static IP of 0.0.0.0). Once the desired WAN port ip settings have been configured, follow the steps below.
- In the Zyxel's web interface go to Configuration() → Network → Interface and click on the Bridge tab.
- From the bridge menu click on the Add button to insert a bridge rule.
- Enable the bridge interface and enter the necessary info:
- "Interface Type" needs to be set to External
- "Interface Name" should be set in the following format: br<number> (ex: br0, br1, br2, etc.)
- "Zone" needs to be set to WAN
- In the Member Configuration select one of the WAN (GE) port connections and select an internal interface you wish to bridge, LAN1, LAN2, DMZ, GE Port from the AVAILABLE list and move them over to the MEMBER list.
- Set the "IP Address Assignment" to Use Fixed IP Address and enter the static IP info.
- Click the OK button to apply/save the settings.
Any device that you connect to the DMZ (GE) port(s) will now bypass NAT and have direct access to the public network. All devices connected to the bridge will need to be manually configured with an IP address within your public IP block.
