Hi everybody.
I have small network at home with two machines connected to the net
via ADSL. That means Dynamic IP, though not changing very often.

"odin.swedehost.com" running FreeBSD 4.8-RC #0 Sun Mar 16 2003
Two NICs. xl0 " DHCP " and "NAT-interface", acting as a gateway, doing NAT.

At bootup I get this message:

What's worry me is the " route: bad address: YES " part.

Does it mean that I have a bad address in my routingtable ?
I have tried to do " route -n flush " several times and rebooting.
Everything is working the way it's supposed to, I think :-)
I mean routing, NAT, mailservices etc.

Preciate some enlightenment on this subject.
