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@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@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@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.
