While trying to re-install FSNavigator I stumbled across a problem. While configuring my router to forward a port for FSNav I found that my router (a Zyxel P-2602R-D1A) doesn't allow IP addresses in the fs.netfrag.org format. It does allow 85.10.244.109 but that's the old servername. How to forward to fs.netfrag.org? Same goes for my FS9 which has it ports still forwarded to 85.10.244.109.
Crash

PS Don't come up with: throw your router against the wall and use a normal modem. I can't use a modem....
