Problems with connecting to server

[Darth Irule]

Hello,

Today I attempted to set up a tekkit server. Got everything installed ect.. only problem is when I try to connect to it with my external IP I get a Failed to Connect To Server, Connection Timed Out:Connect error

I have the port 25565 open and I tested that it was open.

I added exceptions in my firewall for the ports aswell as java.

I restarted my computer a bunch of times.

I am using my external IP and it is not changing.

I am able to connect to the server with localhost.

My friends have the same problem when connecting to the server.

In the server properties the serverip is blank.

Ive been searching for a long time now to see what this is happening and I just cant see to figure out why.

Anybody have any ideas?

Edit:

This is for Tekkit Classic. I checked my port status with this site. http://www.yougetsignal.com/tools/open-ports/

Port shows as open while server is up but shows as closed when server is not up.
