firewall rules when joining nodes

[sannsio]

Hi Folks,

I want to build a Proxmox Mail Gateways Cluster. Can someone tell me which ports/protocols are being used when one node joins another node?

Thanks,
Sanni

In addition to what's documented in: https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#firewall_settings
Cluster nodes need to be able to connect on TCP/22 (ssh) and TCP/8006 (pmg-api) to each other.

I hope this helps!
