FireBrick 2700 Configuration run-through: Difference between revisions
The previous config will put the FB on 192.168.1.1, and allow the FB to route IP packets between your LAN subnet and the 192.168.1 subnet. However, at this stage, you may find you are still unable to ping the modem on the WAN port.
For example, on the ZyXel P-660R, you will have configured the IP and Netmask on the 'LAN' tab. But there's no 'Gateway', so we must go to 'Advanced' -> 'Static Routes' tab, and create one. Enter it as follows: IP, Mask = base address of your internal LAN; eg: 81.xx.xx.0, 255.255.255.192. The 'Gateway' address is pointing back at the FB, eg 192.168.1.1. Check the box to Activate the route, hit the 'Apply' button, and that's it done.
