Pexip Infinity port usage and firewall guidance
The diagrams and tables below show the ports used when the Management Node and Conferencing Node connect to other devices.
Firewall, routing and NAT guidance
Note that in all Pexip Infinity deployment scenarios:
- All Pexip nodes must be fully routable to each other (full mesh) in both directions. This means that the Management Node must be able to reach every Conferencing Node, and each Conferencing Node must be able to reach every other Conferencing Node.
- Any internal firewalls must be configured to allow UDP port 500 and traffic using IP protocol 50 (ESP) in both directions between all Pexip nodes.
- There cannot be a NAT between any Pexip nodes.
When a secondary network address is configured on a Conferencing Node:
- The primary address is always used for inter-node communication to the Management Node and to other Conferencing Nodes.
- The secondary address is always used for signaling and media (to endpoints and other video devices).
- You can have a mixture of any number of single-interfaced and dual-interfaced Conferencing Nodes, providing all nodes can communicate with each other via their primary interfaces.
