Default Port Assignments

Nx Support
Updated

This guide outlines the default ports and protocols used for communication between system components, including clients, servers, and cameras. Use this information to configure firewalls, routers, and network security settings.

NOTE: The values in this table are default settings and might differ based on your specific installation or custom network configuration.

Overview

Connection / Component Port Protocol Description
Client to Server 
(Desktop, Web, Mobile)		 7001 TCP Primary port for connecting to the media server.
Server to Server 
(Hive Sync)		 7001

TCP

 

 Facilitates database synchronization and traffic routing between servers in the same system.
Server Auto-Discovery 5353, 3702 UDP Used for mDNS (244.0.0.251) 
and ONVIF/WS-Discovery (239.255.255.250).
Direct Remote Connection 7001 TCP Required for internet access without cloud relay; requires port forwarding on the router.
Cloud-Based Connection See Description Various Please, refer to the Firewall Passlist article for a full list of FQDN adresses, IP addresses, and ports. 
Server to Camera (Control) 80, 443 TCP Standard ports for web interface access (HTTP/HTTPS) and ONVIF commands.
Server to Camera (Media) 554 TCP/UDP Default RTSP port for video and audio retrieval.
Server to Email Service Variable TCP Used for SMTP notifications. 
Common ports include 25, 465, or 587.
Server to LDAP/AD Variable TCP Used for user synchronization. 
Common ports are 389 (LDAP) and 636 (LDAPS).
Ephemeral/Dynamic 49152–65535 TCP/UDP Temporary ports assigned by the OS for outbound connections.

Connection Details

Client and Server Communication

By default, the media server uses port 7001 for most traffic. This includes client-to-server interactions and synchronization between multiple servers within a "Hive."

If you are accessing the system remotely without a cloud relay, you must configure your router to forward port 7001 to the server's internal IP address. This port number can be changed per Server in the WebAdmin Settings tab.

Device Discovery

The system uses multicast protocols to discover cameras and other servers automatically:

  • mDNS (5353): Used for general network discovery.

  • WS-Discovery (3702): Used specifically for finding ONVIF-compliant devices.

Camera Integration

The server interacts with cameras using two distinct streams:

  1. Management Stream (Ports 80/443): Used to change settings and send control commands via ONVIF or Vendor Specific API requests.

  2. Media Stream (Port 554): Used to pull the actual video and audio data via the Real-Time Streaming Protocol (RTSP). This default port can be changed in the Expert tab of the Camera Settings menu.

Dynamic (Ephemeral) Ports

In TCP/IP networking, the operating system automatically assigns dynamic ports (ranging from 49152 to 65535) when an application initiates an outbound connection.

These ports are temporary and are released once the session ends. Ensure your firewall allows outbound traffic on these ports to maintain stable connections to external services, such as cloud relays or update servers.

External Services

For features like Email notifications or LDAP/Active Directory integration, the ports depend on your external provider's configuration. Ensure these ports are open on your outbound firewall to allow the server to communicate with the domain controller or SMTP relay.
