Ports refuse to forward

[mroedesigns]

Im trying to forward port 54269 for my game, but I cant get it to work D; I've tried forwarding it both with my internal IP (192.168.0.3) and my external IP, but neither is working, I'm using CanYouSeeMe.org to check if the port is available, but it of course is not.

Here's the fields that my router has for forwarding ports.

(click to show/hide)
LAN port and IP information.
  Starting Port: (I put 54269)
  Ending Port: (Again, 54269. I've also tried starting on 268 and ending on 270 but that didnt work either.)
  Protocol: (TCP)
  LAN IP Address: (I've tried both internal and external IP here)   


2. Set the remote port and IP information. (Optional)
  Starting Port:
  Ending Port:   
  Set Remote IP Address:    (0.0.0.0 will use any IP Address)

I leave those last three blank, with 0.0.0.0 in the remote IP for any.
I don't know what I'm doing wrong :/
