A while ago ive used a similar configuration, what ive done was: - create additionall routing table add all regular entries to it with changed default gateway for the second provider like: ip route add xxx.xxx.xxx.xxx via yyy.yyy.yyy.yyy table 2 ... ip route add default via IP_OF_2ND_GATEWAY table 2 - mark desired traffic with iptables iptables -I FORWARD -s LAN_NET/MASK -p tcp --dport XXX -j MARK --set-mark 2 - use ip rules to direct marked packets via alternative routing table ip rule add fwmark 2 table 2 - and maby add additionall rule to make all packages originating at eth1 ip to go via table 2 ip rule add from ETH1_IP table 2 should be more or less something like this, though i dont recall if syntax was exactly like ive wrote above. big dissadvantage of this solution is utilisation of marks, that might be used for another purpose. -- Radek 'Goblin' Pieczonka _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
