PCAP WebRTC Analyzer
Upload PCAP, PCAPNG, or Wireshark text export to find WebRTC, TURN, STUN, DTLS, RTP, VPN, and firewall indicators.
This lightweight PHP tool scans for common protocol strings. For full packet parsing, add tshark server-side.
Troubleshooting Tips
- If STUN is missing, UDP may be blocked.
- If only relay is used, check VPN, symmetric NAT, or enterprise firewall.
- If DTLS is blocked, WebRTC media cannot establish.
- If WHEP returns 405, the URL probably does not accept POST application/sdp.
