You are my hero! ;-)

This works perfectly fine...
  | vuurmuur -b | grep "\-\-set\-mark" | sed "s/FORWARD/PREROUTING/g" | xargs
...with one exception: obviously all rules that have outgoing interfaces
attached won't work; in my case there are several rules generated from that
single rule: (eth: lan, eth1/eth2: inet; ips written as lan/24 and inet)

  | /sbin/iptables -t mangle -A PREROUTING -i eth0 -o eth1  -s lan/24 -d inet
  |                -m state --state NEW,RELATED,ESTABLISHED -j MARK --set-mark 2
  | /sbin/iptables -t mangle -A PREROUTING -i eth1 -o eth0  -s inet -d lan/24
  |                -m state --state RELATED,ESTABLISHED -j MARK --set-mark 2
Those cannot be loaded as PREROUTING cannot deal with -o

  | /sbin/iptables -t mangle -A PREROUTING -i eth0 -s lan/24 -d inet
  |                -m state --state NEW,RELATED,ESTABLISHED -j MARK --set-mark 2
This one rule simply does the trick!

  | /sbin/iptables -t mangle -A PREROUTING -o eth0 -s inet -d lan/24
  |                -m state --state RELATED,ESTABLISHED -j MARK --set-mark 2
This rule doesn't work due to -o

  | /sbin/iptables -t mangle -A PREROUTING -i eth0 -o eth2 -s lan/24 -d inet
  |                -m state --state NEW,RELATED,ESTABLISHED -j MARK --set-mark 2
  | /sbin/iptables -t mangle -A PREROUTING -i eth2 -o eth0 -s inet -d lan/24
  |                -m state --state RELATED,ESTABLISHED -j MARK --set-mark 2
Those do not work too (-o)

Ok, so do you think a patch to add that feature could make it into 0.8? :-)

And for the time being I'll just load that single rule manually...
...oh, and I need rules for all non-marked connections before to avoid them
being routed through the same gateway. ;-)

Thank you very much, Victor!
