According to some articles on netfilter I have reading this should work
for basic policy routing.
iptables -A PREROUTING -i eth1 -t mangle -p tcp -d 18.104.22.168 -j MARK --set-mark 1
# echo 204 google.out >> /etc/iproute2/rt_tables
# ip rule add fwmark 1 table google.out
# ip rule ls
0: from all lookup local
32764: from all fwmark 1 lookup google.out
32766: from all lookup main
32767: from all lookup default
# /sbin/ip route add default via 192.168.4.1 dev eth3 table google.out
What I want to do is route all outgoing traffic (people going to google's ip via http(s)) using eth3..
I tcpdump eth1, eth2, eth3 and my net interfaces eth2, eth3 have google traffic on them.. This doesn't seem
to be using my routing rules..Am I missing something?
