I set the GATEWAY=x.x.x.x in /etc/sysconfig/network-scripts/ifcfg-eth1 which is my wan card. Is there any other places it must be set. My isp is bluecom.no and I got this netbios related line when running tcpdump.
a217.118.65.180 > 162.45.10.77.netbios-ns
where the leftmost ip is my wan card ip from my isp.
But the rightmost ip is changing all the time so I was wonder if that netbios-ns is through my maschine and if that port is open?

If you are having trouble with these ports, I would suggest explicitly
blocking them at the gateway, and not rely on ESTABLISHED, RELATED
type conditions. I've seen reports where connection tracking was
confused by these protocols, and allowed traffic when it shouldn't.
But this has nothing to do with masquerading per se.
