Probelems connecting to server

[justjort]

My fried tries to join my server, however after seeing the login screen for a couple of minutes his request gets rejected. We have tried re-installing all the things: java, forge, ftb. We even tried using multimc. We are all running 1.0.2 of the direwolf20 pack.

Here are the logs for server and client:

http://pastebin.com/pQbesp1d (Server)

Note: I have no trouble what so ever, using my local or public IP.

 

on the client this sometimes pops up as well: Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.server.S00PacketKeepAlive

 

Edit: We have tried installing act and morpheous onto the client, in vain

 

I hope someone knows how to fix it

(before you send me to the ftb help desk, I do think that this is a forge related problem and therefore have much more luck finding a solution here)

We need the full client FML log. Not MultiMCs log.

Can he connect to vanilla servers? Can he connect to other modded servers? If I interpret those logs correctly it just looks as if the connection times out (due to his or the server's network connection).

 

He appears not to have any problems connecting to any other server, both vanilla and modded

We have just run the server on my other pc, which worked like a charm.

I am now updating java on the original pc. maybe that fixes it

 

[justjort]

That didn't seem to fix it. are there any other ports used other that 25565? (we used hamachi on he other pc)

[justjort]

Then it definitely sounds like a connection issue between you and your friend's PC. Can he connect if you run a vanilla server on your PC?

Yes, he can even connect to the server using hamachi. i am trying to fix the network issue now...
