Okay do I have open any ports for FSX? If so how would I do it in FS Host Client?
If you still have lovely old FS 9, (FS 2004), it's esy-peasy.... 8-)...!
Just got to "Multiplayer Connect" in FS 9 and type in 85.10.244.109 as the Server address...>...Connect...and you are with us...simple as that...
