You do not need to port forward to share a Plex instance over the Internet. App.plex.tv manages the inbound connections automatically. All you need to do is manage invites to your friends. They log in with their email/password or with Google SSO to app.plex.tv and your content will be available over a secure connection with no port forwarding.
