Well the Comcast cable modem was a dead end. I checked it and DHCP is disabled, and even if it were enabled it uses a completely different subnet. Besides, It would be coming in on eth2 and not eth0. I checked the wireless router in the LAN and it uses the 192.168.3.0/24 subnet for it's DHCP connections. It has a fixed IP of 192.168.0.100 on the LAN interface so I don't know why these IPs would ever be seen by the firewall/gateway box, but this looks like the most likely source.
Waitaminnit. Yesterday you wrote:
Wireless Router Attached to the LAN: The LAN facing NIC on the wireless router has a fixed IP of 192.168.0.100. The wireless interface is configured to assign IPs in the 192.168.2.0/24 range to the wireless hosts using DHCP.
If the wireless router DHCP is setup to assign from 192.168.3.0/24, then that's where the 192.168.3.2 is coming from. Unless your gateway is set to masquerade 192.168.3.0/24, you get exactly what you're seeing.
