Port Forwarding Bug - Working but not working?!?

I've port forwarded numerous times. I follow portforward.com
In-Fact to this exact link: http://portforward.com/english/routers/port_forwarding/Belkin/F7D2301v1/Minecraft_Server.htm

I don't know what I've done wrong.... The last time I hosted a server was quite a while back however have I missed something?

A few files that may be usefull.....

Batch File:

Code:

@ECHO OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles%\Java\jre6\bin\java.exe" -Xmx1024M -Xms1024M -jar craftbukkit-1.1-R4.jar
PAUSE

Server.properties

Code:

#Minecraft server properties
#Mon Feb 20 17:29:12 EST 2012
allow-nether=true
level-name=Modern MineCraft
enable-query=false
allow-flight=false
server-port=25565
level-type=DEFAULT
enable-rcon=false
level-seed=
server-ip=
spawn-npcs=true
white-list=false
spawn-animals=true
online-mode=true
pvp=true
difficulty=1
server-name=Modern MineCraft
gamemode=0
max-players=40
spawn-monsters=true
generate-structures=true
view-distance=10
motd=Has finally returned!

Note: It was working like a few hours ago and I had to re-log onto the server but once I tried it said "Cannot Reach Server"


Thanks in Advance

Additional Information..
People can connect for the first minute its up and then they can no longer connect after that. So once you log out whilst on the server and the first minute has been completed you can't come back on. "Cant Reach Server" message can be found

Latest Reccomended build of Craftbukkit btw as you see in the batch files code.
Also here...

It says that rather then host not found
Then on console it says "/MyIP lost connection"

Can you connect locally? If so, then it is probably a bug with your network. Check for typos if need be.

Can you send a plugin list? The problem might be in there.

If you can't connect locally, try creating a new map. There's a slim chance of this being it, but occasionally a corrupted map can do some whacky things to the server, and the server crashes after a few minutes cause the problem chunk isn't loaded till then.

 

How do I connect localy? I've never had to do this before ? Do I just put in my static ip as the ip address?... I believe it has something to do with a NTP as it gives that message in the security log.

 

Do you host the server off of a personal computer that uses minecraft? That's connecting locally. On the server computer, launch minecraft and type 127.0.0.1 in the server browser. Try connecting and see if that works.

Can you list your plugins?

 

The port checker claims that the port is closed. Will plugins interfere with the port?

Thank You for your help so far. Perhaps I could give you the teamviewer details. No I don't host the server my friend hosts it. He is not much of a software or networking type of guy. He just knows allot about specs and all that. Perhaps you could talk to him.

Additional Note: it's hosted from a laptop. Do I need to use his PC to make the port work?

 

Oh. If the port is closed, then it has to do with the router... To be able to do anything with teamviewer, I'd have to have access to the router's port forwarding page and you'd have to be able to read off an IP from his laptop. If ya can do that, PM me.
