What is the IP address your modem is saying is your external address? Does that match what the port checkers are seeing?
Yes, the PPP in my modem connection summary is the same as the IP displayed on the port checkers. Same IP that Google and various other IP checkers displayed. This is the IP I'm attempting to use when trying to connect to myself externally.
Also, the PPP status under my connection summary says "Connection up".

These new modems have firewalls built into them. Check you settings there. It sounds as if you bypassed this step
Right, good point. I did forget to mention that I have all firewalls off (Windows firewall disabled and the firewall in my modem settings under "Security settings" set to none), at the time of port checking. No 3rd party firewalls or protection installed either. Is there another firewall that I'm skipping over that you can think of?
