Actually Lars,
If you notice the MAC, it's the same as:
ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 209.74.87.1 netmask 0xffffff00 broadcast 209.74.87.255
ether 00:60:08:35:57:4e
So 209.74.87.1 is on ep0 which is on lo0 but gets caught at xl0, according
to this machine.
So maybe a picture will help

This is what I believe to be the current set up. Now that I read the
email mentioning the loop, it's possible that somebody has thrown in a hub
connecting both networks. I know there's one in the closet. I'll have to
go and check.
Ideally, all I'm trying to do is route one class C into my
provider's network. I just want a router, it happens to be running
FreeBSD instead of IOS.
I'll have to go take a look at the cabling setups though. Thanks for the
tips everybody.
