Can only play on Lan, others time out. (end of stream)

Hi. title says it all.
Plugins;
Authorize, dynmap, essentials, homelite, mywarp, antibreak, timeshift,
I tried disabling and friend got to downloading terrain then time out.

system;
Windows 7 *64bit
4gb ram
intel core 2 duo cpu e8400 @3 ghz.
---
Server config

-----------------
Ports are forwarded correctly. Those who are outside my network can view dynmap which is forwarded at the same time as minecraft(seen on port checker aswell.)
Default port.
And btw I can see my friend when he logs in but all he sees is the screen stuck on log in and then times out after some time.

some errors at cmd when without plugins

Code:

Did that and updated, still error.
Code shows the new error with no plugins.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Try, just to test, using a new world (backup/move your world folder and have the server generate a new one).

I'm guessing part of your world is corrupt and causing that problem. Hard to say for sure.

 

It was a new world... had nothing in it(except that I walked around a few times on the lan connection.)
Deleted the world and it did not work.

Other error now in server cmd and still stuck at "loging in", the other error still comes sometimes.

Have you tried with anyone but your friend?

 

I tried with 3 different friends. Sorry that I forgot to mention it.
Just tested the server with Hamachi and it worked so why wont it work usually ?
double checked ports.

 

err.. what?

 

I previously had an error coming from essentials plugin but I removed from this thread (caused because of the login problem.) Still haven't found a solution.

 

Out of curiosity (a theory I've been building for a while), do you friends have routers, or connect directly to the internet?

 

Routers, except one is directly connected to a telesey box (not sure if it's a router or not.)
------edit----
I gave up and managed with help to set it on a virtual linux box. Works now so this has something to do with windows 7 x64.

 

For my test box, on 7, I ended up just completely disabling the firewall. While the new firewall rules are more granular, it's a pain in the ass to do anything simple with it.

 

so no one knows what it means?
