Minor comment: MAC filtering is often of little uie, because it is so
easy to set/spoof the MAC address. We do _monitor_ the MAC and IP
addresses, but being a secure facility, our reaction to an unknown
MAC address or a MAC/IP relationship that doesn't match our records is
to send in the security guards.

All this tells us is that things are not the same. No indication what may
be different, because there is no indication of what you tried to do.

"it didn't work"... What happened? Did the computer catch on fire? What
were the exact error messgaes. What did you try to do? How did that fail?

Not enough information.

What would be more useful to you is to compare the outputs of the
following commands between the working, and non-working Linux systems:
/sbin/ifconfig -a
/sbin/route -n
/sbin/iptables -L
Also look at the contents of
/etc/resolv.conf
/etc/host.conf
/etc/nsswitch.conf
The assumption is that you are ONLY trying to use these systems as clients
and not as servers (if you are running servers, which ones - how are they
configured, what is the contents of /etc/hosts.allow, /etc/hosts.deny, and
/etc/hosts).
