Firewall and NAT settings
For correct operation of the server when accessed from an external network, it is necessary to allow inbound and outbound traffic on the ports used by the server (configure Firewall and NAT rules). The default port values are shown in the table below:
| Port / range | Protocol | Purpose |
|---|---|---|
| 22 | TCP | SSH |
| 443 | TCP | HTTPS |
| 1719 | UDP | H.323 – registration, admission and status (RAS) |
| 1720 | TCP | H.323 – call signaling (H.225) |
| 3478 | UDP | STUN (for WebRTC operation / NAT traversal) |
| 5060 | UDP/TCP | SIP |
| 5061 | TCP | SIP TLS signaling |
| 20000–65000 | UDP | Media (RTP/RTCP) |
| 1024–65000 | TCP | H.323 (H.245) |
