Your problem is interesting because I can access my Cable Modem IP
address of 192.168.100.1 from inside the LAN on my M0n0wall. I currently
have the "Block private networks" rule turned on and it works fine. I
did nothing special to get this to work.

Are you using the correct address for your cable modem. Most of the
modems I have seen use 192.168.100.1 not 192.168.0.1.
