TCP 3479
Synopsis
- Sony PlayStation Network uses TCP 3479 (along with 3478 and 3480) for PSN connectivity on PlayStation 4 and PlayStation 5, covering services like multiplayer sessions and party/voice chat; Sony’s support documentation lists these as required ports.
- TCP 3479 is also the registered port for 2Wire RPC (service name: twrpc), used by 2Wire/Pace home gateways deployed by AT&T U-verse for device management/diagnostics.
- Real-world examples include PS4/PS5 consoles connecting to PSN, and AT&T U-verse 2Wire gateways such as the 3800HGV-B or 2701HG-B exposing the twrpc service on 3479/TCP.
