Ethernet Port Numbers

CueServer 2 uses several different Ethernet protocols to communicate with other devices on the network.

The following table lists each of the TCP and UDP port numbers used by CueServer’s various features and facilities:

Port Protocol Service Direction Description
22 TCP SSH Incoming Terminal access to CueServer’s internal command shell. This is only necessary for advanced users or factory troubleshooting.
23 TCP Telnet Incoming [Depreciated] Terminal access to CueServer’s internal command shell. This is only necessary for advanced users or factory troubleshooting. No longer active beginning with Firmware Version 3.1
68 UDP DHCP Bidirectional Used by DHCP service if enabled. Not active if CueServer is given a static IP address.
80 TCP HTTP Incoming CueServer’s internal web server. Used for communication with CueServer Studio, virtual touchscreens, Insite touchscreens, user’s custom web content, and the CueServer web-based API.
123 UDP NTP Bidirectional Used for polling Network Time Protocol servers. Only active when NTP service is enabled.
5568 UDP sACN Outgoing Streaming ACN (sACN) data packets. This port is only active when configured to receive and/or transmit sACN protocol.
6038 UDP KiNET Outgoing KiNET v1 and v2 data packets. This port is only active when configured to receive and/or transmit KiNET protocol.
6454 UDP Art-Net Outgoing Art-Net data packets. This port is only active when configured to receive and/or transmit Art-Net protocol.
52737 UDP CueServer Bidirectional Used for CueServer auto-discovery, CueScript commands, and CueStation Hub Protocol.

Port Forwarding for CueServer Studio

To provide access to a CueServer for CueServer Studio remotely, it is only necessary to open Port 80. All communication between CueServer Studio and CueServer devices occurs over this port, with the sole exception of auto-discovery. The auto-discovery function cannot work across different networks, so it is necessary to use the “Add Remote” feature in Studio to add the CueServer to the list of available devices.
