Hi All,
I'm setting up a box with one default route and another handling only
web connection.
Here my conf :
iptables -t mangle -A PREROUTING -p tcp --dport 80 -j MARK --set-mark 3
0: from all lookup local
32766: from all lookup main <- wich contain route to my lan and
internet inferfaces
32767: from all fwmark 3 lookup webbox <- wich contain only the
default route for wen traffic
32768: from all lookup default <- which contain only the other default
route
The problem : Packets to port 80 go tough the webbox thanks to fwmark
but the reply from webbox don't cross the fw...
What's the reason ?
Thanks !
Guillaume from france
