Tom,

thevenin:/etc# cat /proc/sys/net/ipv4/ip_forward
1

I did that explicitly.  I probably should have installed shorewall but
since all I want to do is forward all traffic between two internal nets I
figured it would be easy enough just to dump a few rules into iptables.

Wrong!

thevenin:/etc/init.d# uname -a
Linux thevenin 2.4.18-686 #1 Sun Apr 14 11:32:47 EST 2002 i686 unknown
