It seems like the config file has been changed even though it still states 3CPE in the filename. 7-Information F504.1 Bridge Ethernet Hook. Failed to learn CPE MAC Address. F507.5 MAC Filters. Add MAC Address can't add entry.
Table is full.
I have my machines set up on an internal network with the machine that the modem is plugged in to being the Connection Server. Running MS Internet Connection Sharing with WinProxy running over that for stability. I don't know why the two are working together but it is a lot more stable than just running each independently. The way I understand the router is that each assigned IP is stored in the router. Technically you do not have an internal network.
