Configure network settings
Pearl Nanos use DHCP to obtain an IP Address over an Ethernet-based network by default; however, you can easily change the network settings.
Network ports used by Pearl Nano
The following table lists the default incoming and outgoing network ports.
Do not block traffic over these ports. If you want Pearl Nanos to operate properly, make sure that your firewall is configured to open these ports. Blocking a port will cause the service that uses that port to fail. It is possible to use the Admin panel to change the default ports that are used for some services.
Table 12 Default incoming network ports for Pearl Nanos
| Port (or range) | Protocol | Description |
|---|---|---|
| 22 | TCP | SSH for remote support. See Support. |
| 80 | TCP | HTTP/HTTPS for web-based access to the Admin panel, HTTP/HTTPS API, REST API, HLS streaming (if enabled) and the live channel preview. You can change the default HTTP port value using the Admin panel, see Configure HTTPS. |
| 123 | TCP/UDP | NTP server, if enabled. See Configure a time server. |
| 319 and 320 | UDP | PTP server, if enabled. See Configure a time server. |
| 443 | TCP | HTTPS for the Admin panel and HLS streaming if enabled. Port is open only when HTTPS is enabled. You can change the default HTTPS port value using the Admin panel, see Configure HTTPS. Checks for new firmware versions are over this port, as well as downloading firmware files. |
| Pearl Nano: 554 | TCP | For RTSP/TCP and RTSP/HTTP streaming on your network. See Share a live broadcast stream (HTTP, HTTPS, or RTSP). Note that client video players choose whether they are using RTSP/TCP, RTSP/HTTP or RTSP/UDP. Port 554 is 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. |
| 5353 | UDP | For multicast DNS discovery. See Connect using a DNS-based service discovery. |
| Pearl Nano: 8000 | TCP | For Flash (FLV) live stream and MPEG-TS streaming on your network. See Share a live broadcast stream (HTTP, HTTPS, or RTSP). If streaming is disabled for the channel from Channel > Streaming using the Admin panel, these ports remain open but refuse all external connection requests. |
In addition to the incoming ports, Pearl Nanos use some outgoing connections as follows:
Port 443 - used for firmware update checks and downloads.
Publishing/streaming port - the actual ports used for streaming to a server depends on the server and protocol used. See Streaming to servers, CDNs, and other devices.
AFU file recording transfer port - the actual ports used for AFU depends on your configuration. See Automatic file transfers.
