Trouble Forwarding Ports

Hello Forums, I Seem to be having trouble forwarding my ports, My router model is a D-Link DIR-615. (If needed by PC Specs are down below) When i go into my router and i forward the ports, the forwarding doesn't work, Here is what i know

-Computer IP Is the correct IP that the port is being forwarded too
-Windows Firewall is Off
-Restarting the Router/Computer Multiple Times
-The router says the ports are forwarded
-I have forwarded the ports to a laptop of mine and that seemed to work
-I tested the ports on this site Open Port Check Tool - Test Port Forwarding on Your Router
-That site told me that the forwarding to my laptop worked, but not to my desktop

Could anyone help me?

When you forward a port lets say port number 22 for an ssh connection you have to specify an ip address lets say 192.168.2.1. Now if you use your external ip address with port 22 it will look for 192.168.2.1 listening for a connection. If you're on 192.168.2.5 the port will not be forwarded to the computer. It will only go to 192.168.2.1.

I hope that make since it sounds like you did it right for your laptops ip addresss

I did that, it still didnt work. Does anybody else have any suggestions?

Bump, Im still looking for an answer to this.

What port(s) are you trying to open. Do you have a program listening for a connection?

Does the target computer have a fixed local IP? It needs to be static for port forwarding to work with the correct computer.
Also, you can try doing a telnet to your public IP on the targeted port to test if anything respond to the connection. If the laptop is still answering it, most likely you have mixed the IPs of the computers, or if nothing does, maybe an antivirus/firewall is blocking it.

The IP Is static, and i quadruple checked the IP's. The Windows Firewall is completely disabled, same with my antivirus,

Are you trying to forward the same ports on the laptop and the desktop?

Also are what A/V are you using?

The ports are different, the ports on the laptop are just 200, and the ones for the desktop are on a previous post, and my AV is microsoft security essentials

On the desktop type open a command prompt and type "netstat -a" no quotes post the output or just look for the port you opened with listening on under state.
