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
