How does plex obtain external IP address?
I don't know if it uses an HTTP(S) GET request or the like. I'd like to know how, because I have a VPN and I don't want to send my plex traffic through it. But simply allowing port 32400 to bypass the VPN is not enough, because it accidently registers the VPN IP instead of my ISP one.
Do I need to allow the plex server to communicate out on port 80 and 443 as well?
