Internet-Security.com UDP port 5000 details

VTun (Virtual Tunnel) VPN commonly uses UDP/5000 by default when configured for UDP-based tunnels.
Riot Games’ League of Legends uses UDP ports 5000–5500 for in‑game traffic, so UDP/5000 is used on some client sessions.
Media streaming tools like GStreamer, FFmpeg, and VLC are frequently configured in real deployments to send/receive RTP or MPEG‑TS over UDP/5000 (a de facto convention in many example pipelines and setups).
Some IP camera/NVR deployments and custom RTP pipelines also use UDP/5000 for video streams, following the same convention from common streaming toolchains.
