Accessing bridged modem through EdgeRouter

10 Feb 2016 ⚠️ This post is over 8 years old. It may no longer be up to date.

I needed a small tweak to my EdgeRouter config to let me connect to my bridged VDSL modem. The EdgeRouter is connected to the modem on eth0.

The modem uses 192.168.1.254/24 by default, so the first step is to give eth0 an IP on the same network. Then we need a NAT masquerade rule to NAT traffic for the 192.168.1.0/24 network through eth0.
