Networking and TCP/IP Ports

_images/ports_connectivity_header.jpg

Overview

For optimal operation of Omniverse applications, certain TCP/IP ports must be opened between components and/or servers. Review and reference the list below to ensure proper communication is allowed. If network changes are required, please consult your IT or Information Security Team for proper advisement.

Warning

Many of the listed ports can be customized, however some must remain as specified. For additional information, review the related interface or configuration files (.env) for the Omniverse service being configured.

Nucleus Workstation

These ports are used with Nucleus Workstation:

Purpose
TCP Port
Nucleus Core and Discovery API Ports
3001, 3009, 3333
Prometheus Metrics Port
3010
Nucleus Tagging Service Port
3020
Nucleus System Monitor Ports
3080, 3085
Authentication Service Port
3100
Authentication Web Port
3180
Search Service Port
3400
Cache Services Port
8891
Cache API Port
8892
Nucleus Navigator Port (within Launcher)
34080
Omniverse Drive Progress Interface Port
59624

Warning

Locally installed firewall software (e.g., Windows Defender, ufw, etc.) may block communication to these ports and configuration changes may be required.

Enterprise Nucleus Server

These ports are required for Clients and services to connect to an Enterprise Nucleus Server:

Purpose
TCP Port
Web Port*
80
API Ports
3009, 3019
Prometheus Metrics Port
3010
Tagging Service Port
3020
Large File Transfer Service Port
3030
Authentication Service Ports
3100, 3180
Discovery Port
3333
Search Service Port
3400
Service API Port**
3006
Meta Dump Port**
5555

Note

If your Enterprise Nucleus Server is using NGINX or a similar ingress router/gateway, TCP 443 inbound to the gateway is required and the gateway will then need to communicate with the Enterprise Nucleus Server on the above ports.

* It is recommended that the Web Port be changed from 80 to 8080 if you are using an ingress router/gateway to avoid confusion.

** These ports are required for Nucleus Tools backup only and are disabled by default.
