So Basically its as mentioned. I've tried port forwarding and checking using a web based port checker tool and all the ports I have tried come back closed. I've tried forwarding using upd,tcp, and both with all of the same results. After forwarding I checked which ports were being forwarded in the UPnP/NAT tab and only ports added by UPnP were displayed are forwarded. I've also tried rebooting the router without any new results.

Any insight why none of my ports are being forwarded would be appreciated

Add the custom port forwarding in the Port Forwarding->Basic area.

Make sure you click save before you leave that page.

I'm not that much of a newb =P

I've made sure to hit save before I leave the page and wait for it to reload.

I'm looking at the UPnP page because it will show there what ports are actually forwarded.

Wrong. It does NOT show the manually forwarded ports. It only shows what it says - ports forwarded via UPnP/NAT-PMP.

To see manually forwarded ports, run the following iptables commands:

iptables -nvL; iptables -t nat -nvL

Well this is where my port pops up, but the port checker tools still find it closed. I've tried with a few different port tools… all web based however.

You need to actually have service(s) on your 192.168.1.2 box listening and responding on port 5121 when trying to test it.

so I need the program/service open and running before testing the port?

Yes.
