Hi all, I need to route local generated packages depending on which tcp or udp service I need to use. To accomplish this I have configured two routing tables: [root at lothlorien ~]# ip ru ls 0: from all lookup 255 32762: from all fwmark 0x2 lookup FirstLan 32763: from all fwmark 0x1 lookup SecondLan 32764: from 172.25.80.10 lookup SecondLan 32765: from 172.25.70.18 lookup FirstLan 32766: from all lookup main 32767: from all lookup default My routing tables: [root at lothlorien net]# ip ro show table FirstLan 172.25.70.16/28 dev eth1 proto kernel scope link src 172.25.70.18 default via 172.25.70.30 dev eth1 [root at lothlorien net]# ip ro show table SecondLan 172.25.80.0/24 dev eth1 proto kernel scope link src 172.25.80.10 default via 172.25.80.1 dev eth2 And my iptables rule is: iptables -t mangle -A OUTPUT -p udp --dport 53 -j MARK --set-mark 1 But this doesn't works. This host is CentOS 5.5 based with two interfaces. What am I doing wrong?? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
