The simplest way to reach Plex without opening an internet-facing router port is Tailscale on your Plex host and your own remote devices. For external viewers who cannot join the tailnet, the answer is different.
You do not need new hardware to avoid public port forwarding in most cases. First decide who must reach the server: your own devices, a few trusted people, or many ordinary Plex clients.
What to do next
Follow these steps before changing your NAS or buying new hardware.
Decide whether every remote device can use Tailscale.
Install Tailscale on the host or provide an authorized subnet route.
Confirm Plex responds over the tailnet IP and can stream your normal media.

Detailed guide: How to use Plex without port forwarding
Answers to the questions that matter before you change your setup.
Can Plex remote access work without port forwarding?
Yes, when the remote client has a private route into the network running Plex. Tailscale creates that route between authorized devices, including in many CGNAT environments. You do not need to expose Plex to the public internet just to watch content on your own phone or laptop. Both Plex authentication and tailnet access controls should remain enabled.
What is the easiest method for a NAS?
Install the official Tailscale integration supported by your NAS platform and join the NAS and viewing device to the same tailnet. Check that the remote client can reach the NAS Tailscale IP. Then test the Plex server on the internal port 32400. If Plex runs in a container, confirm the container port is published on the host or otherwise accessible from the tailnet.
When do I need a subnet router?
A subnet router can advertise a small internal network to your tailnet when the Plex host itself cannot run Tailscale. For example, a NAS may store your media while a separate server hosts Plex, or a legacy device may have no Tailscale app. Scope the advertised routes carefully; granting every remote device broad LAN access is unnecessary and raises risk.
What about Plex Relay?
Plex Relay can provide indirect connectivity when direct routes fail, but it is a fallback rather than the preferred way to stream high-bitrate video. Plex documents rate limits on Relay streams. A media library with large 1080p or 4K files should be tested over a real direct path before you rely on it for travel or family streaming.
When is public access still better?
If many friends or household members use devices that cannot join a private tailnet, ordinary Plex remote access with a reachable public connection can be more practical. Ask your ISP about public IPv4 if you have CGNAT. Avoid exposing a NAS admin portal or unrelated services just to make Plex reachable.
Frequently asked questions
Does no port forwarding mean no authentication?
No. Use Plex account access and tailnet authentication together; private networking does not replace user permissions.
Is a more powerful NAS required?
Not for the private network itself. Upgrade hardware only if Plex playback, transcoding or storage needs justify it.
