IP Address Problem

[davidgsmith]

Hi Everyone!

Not sure where to start... but I'll give as much info as I can.
Windows XP Pro SP3
I use Cricket wireless broadband for my internet connection.
When I went into Control Panel>Networks and right clicked on my cricket connection's properties it showed that I had 2 IP addresses.
One is called a Client IP Address and the other a Server IP Address

As far as browsing, downloading, uploading, everything is fine.
I like to play computer golf... and I went to a website called Game Spy
www.gamespy.com to join others for online play.
At this website you can play many games. For my particular game, you go into a "LOBBY" and meet up with other players and someone will volunteer to host the game, and the rest will join. Once the host "launches", the website starts the game on your computer and you all meet in the game's lobby then go on and play.


I could not join a game, the website started my game on my computer, but I got an error msg stating that I was not able to connect with lobby data.

So I tried to host and got this warning:
"Game Spy has detected that your computer's internal IP address xx.xxx.xx.xx is different that it's external address cc.ccc.cc.cc. (did not provide actual addresses)
This may be caused by firewalls, a NAT proxies or other unusual network configurations and may prevent you from hosting a game...

I am clueless regarding networks, IP addresses and such. I found something about NAT (boy all these abbreviations kill me !) and I think this is what Cricket is running.
Anyone have any ideas how to get around this? Settings changes? Anything?

As always, your help is always gratefully appreciated
