Sorry if this is an easy question.  I'm trying to join any of the non-password multiplayer servers using a specific IP/port obtained from this http://www.digitalcombatsimulator.com/en/personal/server/#allservers.  However, I always get a "Server offline" message when I try to connect.  I can ping the IP address from a windows DOS prompt.  So I'm not sure what's wrong.  I can only make a successful connections to a multiplayer server if they are listed in the in-game server browser.  However, I only get a list of 30 or so servers in that, and most need a password. I would like to connect some of the servers from the server webpage.
