Hi Cameron... On FIRST glance it seems to me that someone on your
network has hijacked the IP address of the LAN interface of your m0n0wall.

Try this:

- UNplug the m0n0wall from the network
- Open a command prompt on a machine that is connected to the network
- Type:  ping

If you see a return then track it down. This is your culprit.

Alternatively, you can change the IP address of your m0n0wall, but I
would hunt down the machine to get closure. :)
