Undoing VPN port forwarding issue

[Reino]

I wanted to post here to see if I am having an obvious issue.

I have been port forwarding and using the NAT stuff for years now with no issues.  Recently, I have run into a problem where I can't get BiglyBT NAT working anymore. I added the test messages at the bottom.

This all started when I tried using the VPN Helper add-in to set it up with my Private Internet Access VPN.  I was able to get the NAT working through the VPN and everything worked fine until I wanted to undo it for speed. The issue arose from detached the PIA and VPN Helper, and now I can't seem to figure out what is blocking the port. I have all my OS side firewalls off for troubleshooting, and my qTorrent is still NATing perfectly on a different port.

Are there any obvious ideas as to what is going on? I know PIA leaves quite services in the task manager.

I am wondering if I left something lingering in the background or something.

Any ideas?
