The modem, or ADSL router in bridge mode, will also have a LAN IP that you can use to get to it's config pages etc. eg, the ZyXEL P660-R will still have a LAN setting, with an IP set. For the purpose of this example, let's assume the P-660R is on 192.168.1.2 mask 255.255.255.0. |

In order to talk to the Modem from the LAN side of the FireBrick, a Subnet on the FireBrick needs to be made. This subnet would be on the WAN Interface, eg: |

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. THis is because although packets from your 81.x.x.x address are correctly routed to the modem, the modem itself knows no route back to 81.x.x.x. It know nothing of the FB. SO we need to tell it by setting a static route. |
