Port forwarding cho Plex Media Server
Các cổng cần mở
32400TCPPlex Media Server primary port. Plex usually negotiates NAT automatically via Plex Relay — manual forward is only needed for direct/remote access.
Tại sao cần port forwarding?
Plex tries UPnP first; if your router blocks UPnP or you want bandwidth-controlled direct access, forward 32400/TCP to the Plex server. Direct connection avoids the relay bandwidth limits Plex puts on accounts.

Cảnh báo bảo mật
Plex authentication is account-based, so the exposure is bounded — but still keep Plex up to date (CVE-2021-31716, etc.) and use a strong Plex account password with 2FA.
