-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 If I understood your question correctly, I'd suggest you use iptables instead of routing etc. Set up a firewall which prohibits some traffic depending on MAC source while it allows others. Ie, set up the rules which allows traffic with iptables in a way like this: iptables -A FORWARD -s 192.168.1.0/26 -j ACCEPT iptables -A FORWARD -s 192.168.1.64/26 -d 10.1.1.1/32 -j ACCEPT # what kind of access? etc, and then set up a policy of DROP on the FORWARD chain. For more on this, check out the howtos and tutorials etc on http://netfilter.samba.org/.
