I'm hosting a game server on my laptop running Ubuntu 10.04.

My friends can connect to the server completely fine, but when I try to access it, I get a "Connection refused: connect" error. All the ports are open, but I have a feeling this has something to do with my router (Buffalo Nfiniti WHR-G300N V2). I also cannot access an Apache server running on the laptop, although others can.

Any help will be appreciated. Thanks in advance.

This question came from our site for system and network administrators.

How are you trying to connect? Are you using localhost, the DNS name, etc.? – Redmumba Sep 12 '10 at 23:50
If you're trying to connect to the external IP then the answer chris provided below is probably the issue. – Dave Holland Sep 13 '10 at 0:00

Try accessing via your local IP rather than the public IP/name that you provided to your friends.

Your router probably dislikes you attempting to connect to its external IP from the Internal network.

Thank you. I haven't really used stuff in the local area network before, so this came as a little "surprise" to me. – Dragory Sep 13 '10 at 0:01
