strange thing big_smile after 2 hours of playing batllefield2 port forwarding stops working
linksys wrt 54GL kamikaze with standard settings, qos-script
and
iptables -t nat -A prerouting_wan -p tcp --dport 11074 -j DNAT --to 172.18.18.18:11074
iptables        -A forwarding_wan -p tcp --dport 11074 -d 172.18.18.18 -j ACCEPT
iptables -t nat -A prerouting_wan -p udp --dport 11074 -j DNAT --to 172.18.18.18:11074
iptables        -A forwarding_wan -p udp --dport 11074 -d 172.18.18.18 -j ACCEPT

added to firewall.user
what is wrong?
/etc/init.d/qos restart no go sad
same with firewall
when i restart router everything goes back to normal

May be the port+x bug... try using --to ip instead of --to ip:port if the port doesn't change.

The discussion might have continued from here.
