Hello,

  I use Adelphia's cable service for internet access. I currently use a 
Linksys router for my service, but wanted to setup a dedicated firewall 
with m0n0wall on an old 90mhz machine.

  I've gotten everything setup on the firewall so it works perfect on 
the LAN side, and when connected to the Linksys router running under 
DMZ, works like it should. Allows internet access, filters the correct 
packets, traffic shaping looks good. But when I attempt to connect 
directly to the cable modem (Motorola SB5100), both with normal MAC and 
with spoofed MAC, it will not retrieve an IP while set with DHCP. If I 
set to Static with the IP/Gateway that the Linksys router uses, it still 
won't work.

  Any suggestions for how to resolve this problem? I really like 
m0n0wall, but it defeats the purpose if I have to use a linksys router 
in front of it.
