I'm trying to stream games over the internet for me and a friend.

Connecting with my Android phone via my local network works fine.

Trying to add a computer manually with an IP address does not.

I went to https://www.showmyip.com/ to get my IP address and entered that, it didn't work. I tried adding the port in the Sunshine web UI after the IP address, that didn't work.

I've read this could be a firewall issue. I disabled ufw and connecting still does not work.

I tried enabling UPnP in the Sunshine web UI, and that didn't solve the problem.

What's the recommended way to connect to a PC manually? They're not very clear about what information is needed, even specifying that we need to include a port would help.
