Network ports used by Networked VGA Grid
The following is a list of incoming network ports used by your Networked VGA Grid system. Depending on the services you are using, you will need to make sure your firewall permits traffic over the relevant ports.
The port numbers listed below are the default faults for these services. In many cases, you can use the Admin panel to change the port used for this service.
| Port (or range) | Protocol | Description |
|---|---|---|
| 21 | TCP | FTP server, if enabled. |
| 22 | TCP | SSH for remote support. |
| 80 | TCP | HTTP for the Admin panel, HLS streaming if enabled. |
| 123 | TCP/UDP | NTP server, if enabled. |
| 319 and 320 | UDP | PTP server, if enabled. |
| 443 | TCP | HTTPS for the Admin panel, HLS streaming if enabled. |
| 554 to 554+(x-1) | TCP | For RTSP/TCP and RTSP/HTTP streaming on your network (where x is the number of channels configured). The number of ports used depends on how many channels you have with RTSP streaming enabled. *Ports 554 and 555 are also used for internal communications. If streaming is disabled, these ports remain open but refuse all external connection requests. |
| Random in range 32768 - 61000 | UDP | If the client video player chooses RTSP/UDP, it will negotiate 4 random UDP ports (two for audio and two for video). The port range is dependent on the OS of the client video player and can change with updates to that OS. |
| 1900 | UDP | UPnP server (for UPnP discovery), if enabled. |
Random in range | TCP | UPnP media server, if enabled. Each time the UPnP server is started, a random TCP port in this range is used to enable connections with other UPnP devices. |
| 5353 | UDP | For multicast DNS discovery. |
| 5557 | UDP | Epiphan proprietary discovery method for VGA Grid HD Encoders. |
| 8000 to 8000+(x-1) | TCP | For ASF, Flash and MPEG-TS streaming on your network (where x is the number of channels configured). The number of ports used depends on how many channels you have with streaming enabled. *Ports 8000 and 8001 are also used for internal communications. If streaming is disabled, these ports remain open but refuse all external connection requests. |
In addition to the ports listed above, there are also outgoing connections as follows:
- for publishing (Stream to a server) - actual ports used is dependant on the server and protocol
- for File and recording transfer - actual ports used is dependant on your configuration
- remote support (when in use) - port 30
- firmware update (checks and downloads) - port 80
