I find it best to not filter too much for the in-game browser. Also, the IP changed at the beginning of the year to 209.222.20.114, (it had been x.x.x.115). I just filter on Same Mod.
I know, this is a big "duh", but as an admin I find people don't always use these... FAVORITES. It's a good idea to put any FH2 servers you like into your Favorites. The server may be down or something, but you can always confirm by checking its status or trying to join it from your Favorites list. FYI, if you add a Favorite and later CTD out of the same session of FH2, it won't remember you set that; so save, one needs to properly Quit from FH2.
There is one interesting feature on Favorites, (although not quite as good at ALT-F4) ... when in Favorites, click the Refresh button. It will clear the screen of them and you won't see them again until you restart FH2. If you want to do a Refresh while in Favorites to actually do a refresh, then single click on the favorite server in the list and it will update that server's status.
