	I'm running FreeBSD -current so there isn't a GATEWAY option
available in the kernel anymore but I do have sysctl on in my sysconfig.

	Ah okay, let's imagine I only have one machine now and I wanted to
do my own advertising of static routes.   So if my incoming connection 
was 198.94.103.34 and I wanted my machine as the gateway as well as known
as 205.167.165.120 which is my class c network instead of the
198.94.103.34 when connecting to another machine on the net and have the
routing broadcast from my machine to the rest of the net, what do I need
to do exactly?  My machine has a 3Com Etherlink III ISA Combo card now but
it's not connected to anything.  Also, what should my ifconfig lines say
for lo0 and ep0?
