Well, i can only say last time i used PGPfone was in 2014, with a friend.
We both used a website that showed us our IP addresses and it worked
fine. We only had to set UDP port 17447 in our routers, for incoming
and outgoing connections.

I currently have no Windows box, otherwise i would try it out again
and let you know.
