3. Add rule:

• Port: 32400

• Protocol: TCP

• Local IP: IP of your Plex server

• External Port: 32400

4. Save and restart the router

Check if it works

Go to:

Settings → Remote Access → Check Connection

If successful, Plex will show a green checkmark.

Port forwarding is required for stable Plex remote access, especially if you want to stream remotely or share your library with friends/family.

Enabling Secure Connections (HTTPS / SSL)

Go to:

Settings → Network → Secure Connections

Choose:

• Preferred (recommended)

• Required (more secure but can block old devices)

This encrypts your traffic, making your Plex server safer.
