Greetings Dear CentOS List Guys
i have some specific requirement but at this point i only with to know if the following is possible.
1.) CENTOS Machine Acting as Router 2.) Machine is part of 10 VlANs Using 10 local interfaces
Is it possible that i can identify the source traffic and forward it to the specific interface.
i.e.
Remote packet coming from 192.168.21.0 should be forward to 192.168.20.20 (eth1)
Is that possible ?
Thanks / Regards

It's possible, but it is far more typical to have destination based routing. You could look at http://www.novell.com/support/kb/doc.php?id=7008874 for pointers.
What is the end goal, the list might have some pointers that are easier to manage.

I'm actually doing it. The route2 feature can be useful in this case. You can mark the packets and route2 will do the favor for you. It's just different table will be used for the tagged packets. Here is what I use,
1 smtp 2 http 3 ssh 4 lan
$IPTABLES -N Cid6642X27340.0 -t mangle $IPTABLES -t mangle -A PREROUTING -p tcp -m tcp --dport 25 -j Cid6642X27340.0 $IPTABLES -t mangle -A Cid6642X27340.0 -s 10.28.2.238 -j MARK --set-mark 0x1
ip route add 1.1.28.0/24 via 1.1.28.2 dev tun-SINs table smtp ip route add default via 1.1.4.2 dev tun-SIN-EDG table smtp
