[Fixed] Connection from WAN impossible - superboum - 06-09-2012

Hello,
Firt of all, sorry for my english (I'm french).
I downloaded MCServer from your subversion repository and compiled it successfully on my Linux Server running Ubuntu Server.
It works perfectly from my LAN but people can't access to the server from WAN. They are disconnected after "Downloading Map". My configuration (ports,...) is correct because I used bukkit before on this server.
During the connection, the server logged that when someone try to connect from WAN :

So why it doesn't work in WAN ?
Thanks for your answer, I hope I'm in the right section.

RE: Connection from WAN impossible - xoft - 06-09-2012

To me it seems that the connection is dropped at the client side - the server tries to write to the socket and finds it already dropped. Is there an error message that the client produces when connecting over WAN?
Make sure the client on WAN doesn't have any mods installed, those may interfere with the server.

If nothing helps, we'd need wireshark logs. Can you provide a wireshark log of a single attempt to connect from the WAN?

RE: Connection from WAN impossible - superboum - 06-09-2012

Ok, thanks for your answer, I ask this people to try another time and to tell me what was the error. They said nothing, just "Downloading Terrain". I told told them to wait and it worked. They just don't wait enough time during "Downloading Terrain". Because it takes a bit longer with this server. Stupid people, and sorry for the post.
I will remember for the moded client, it could be useful, and to test with wireshark if I have a similar problem.
Thank you very much for your fast answer.
