The very core that 'should' get things going (and works for traffic going out ) is as follows: assuming tables 'adsl' and 'shaw' are set up already in /etc/iproute2/rt_tables (debian) I am using shorewall as a firewall and both eth0 and eth1 are masqueraded to eth2 (local) and eth3 (dmz with the mail server) assuming $GATEWAW_TELUS and $GATEWAY_SHAW have been defined as the appropriate IP's for the gateways of shaw (eth0) and telus (eth1) # setting up default routes in the two tables ip route add default via $GATEWAY_TELUS table adsl ip route add default via $GATEWAY_SHAW table shaw # setting up default route when no branch is taken ip route add default via $GATEWAY_SHAW # mark port 25 traffic coming from mail server iptables - t mangle -A PREROUTING -p tcp --dport 25 -s 192.168.1.2 / -j mark --set-mark 1 # use table telus when port 25 traffic is detected ip route add fwmark 1 table adsl # clear routing cache ip route flush cache Jens _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
