I don't know why you couldn't connect Mr Fozzer ..... I was running FSHost with all the relevant ports open and I have had peeps with 2K2 connect with no problems. Me thinks you are running something which prevents the relevant connections.
It's a funny old do...

My computer is a completely bog-standard set up, nuffin' unusual, 56k modem connected direct to BT's line, running FS 2002 Pro, and using the in-built Multiplayer option in FS 2002.
Only once, in the distant past, have I ever been able to fly with Ozzy, (or anyone else for that matter), and only when he "Hosted" the flight, and I "Joined"...

...!
I have "FS Host" installed, although I could never figure why the FS 2002/2004 Multiplayer option is not used more, as it seems so simple...?
I did a search, to connect to your IP number, but it would not connect, and the "Join" button was always blank....
.....a bit like the expression on my face every time I try out Multiplayer....and fail....

....!
LOL...!
Cheers eno....
