The trick for getting iptables working with RedHat 7.3 is to completely
disable ipchains.  iptables never works even after
/etc/rc.d/init.d/ipchains stop.  The system must boot up without
ever launching ipchains.

The simplest is to:
                      rpm -e ipchains

Then iptables works perfectly in my experience.
(This is consistent with other's experiences on various mailing lists.)

I would suggest though, that this should not obliterate the ability for
system admin's to freely collaborate.

In other words, if a LON-CAPA sysadmin wants to set up a firewall,
providing help is not a totally bad thing (there could be a general firewall
recommendation).  However recommendation can never be presented as an
endorsement then...

LON-CAPA could be helpful but decidedly neutral.  Similar to what we
now do with samba and appletalk.
