Policy routing for IPv4 and IPv6

Policy routing for IPv4 and IPv6

[Marcin Michalak]

Hello,
 I have the following situation: two interfaces, eth0 and eth1 with 
different IPv4 and IPv6 addresses. I want to send some type of 
traffic, let's say web requests over eth1, and everything else over 
eth0.
 I created the table table1 in the /etc/ip_route2/rt_tables by 
putting:
167 table1

Then I issue:
ip[6]tables -t mangle -A PREROUTING --protocol tcp --destination-port 
80 -j MARK --set-mark 1
ip rule add fwmark 1 table table1
ip route add default via 192.168.19.1 dev eth1 table table1

But it doesn't work :-( I also can't issue:
ip -f inet6 rule add fwmark 1 table table1
, because I get: RTNETLINK answers: Invalid argument
 I have kernel 2.6.1 with following modules loaded:

Module                  Size  Used by
ip6t_LOG                5312  -

Any ideas/hints? Would be very grateful. My aim is to make the 
interface selection work over IPv6, but I wanted to start with IPv4 
first.
 Regards,
  Marcin
