Almost.  In "routing" mode the Cisco 675 does DHCP and NAT.  The way
that the 675's NAT works, only well-known port-numbered TCP and UDP
packets get in to my network.

I want to do away with the C675 doing NAT and DHCP and any filtering:
everything comes in to a short segment of CAT-5 cable, connected to some
machine with 2 ethernets.  That machine does the DHCP, NAT, firewalling,
etc on the basement-area-network side, and from its console, I can look
at whatever goofy packets come in, be they TCP, UDP or ChaosNet.

Also, I can see more of what the Qwest DSLAM allows in to the Cisco 675.
