New cluster using Proxmox 5

[Mecanik]

Hello,

First of all I must say that the latest Proxmox 5 GUI is amazing, top notch. I just setup a new cluster using 3 servers, and I have a weird problem.

The moment I enable the Firewall on the "Datacenter" level, the other 2 clusters show as offline. I tried allowing LAN/WAN IP's on the nodes but that did not help.

So now I got to do quite a few steps to disable the firewall on each nodes, and then on the "Datacenter" as well for the nodes to show back as "online".

Can you please tell me if any specific ports or rules must be set ? I really want to use the firewall on the "Datacenter" level.

Thank you!

Also... another question would be, if possible to enable HA for each new VM added as currently I see that you must select manually HA for each VM...

Resolved the HA set for every new VM launched, however I still cannot figure out the Firewall for the "Datacenter".
