RCN has recently pulled a crack smoking move and made the gateways 10.x ip
addresses on their cable modems. It caught me by surprise since I had
just put up a new box and it refused to get on the internet. Anywho, the
easiest way to fix it is to alias 10.254.254.1 (or some other bogus ip) to
your public interface with a netmask of 0xff000000 and then set your
default gateway as normal.
% ifconfig ed0
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 216.164.35.237 netmask 0xffffff00 broadcast 216.164.35.255
inet 10.254.254.1 netmask 0xff000000 broadcast 10.255.255.255

When I get home I'm probably going to switch to DSL, my sanity is worth
more than low cost bandwidth.
