Ports open, but no one can connect

I am programming a server system for a small RPG game made with SFML. This is my first project since we switched our ISP to Comcast and I am having trouble with people connecting to the server. I can connect locally fine and all of the port checking tools say that the port is open, but my friends cannot connect using my external IP. I turned my firewall off on my router and on my computer to see if it'd help the situation at all, but the same thing is occurring.

Comcast gave me an Arris TG862G-CT router.

Here's an image of the port forwarding page:

The port is shown as open, but my client cannot connect:

I'm not sure which language you are using, but many make a distinction between opening a port with the host address 127.0.0.1, 0.0.0.0, and localhost. Many times you will need to use 0.0.0.0 to connect from an external pc where as 127.0.0.1 and localhost are used as a loopback and only accessible by you.
