Using internal network for cluster

[nucode]

Hi,

It seems proxmox defaults on using the public ip address.
Is changing this to internal only way to do via hosts? Do i need just hostname or FQDN (hostname.domain.com) entries in there?
What are the drawbacks?

Change hosts files and reboot to make the changes, or is there a way to do without reboot?

Why is this so? why not just use the IP address specified on the pvecm add command?

Yes that's all!

What are the drawbacks?

No reboot necessary, assumed the ip address exist and works on your host.

Webgui will move to the internal IP?
Hmm, that means i need outside cluster VM for VPN, or a VPN device to access then, or nginx reverse proxy.

I have already added the nodes to the cluster, so if i change the hosts entries, it will move to using those address without reboot?

No sorry this would only work if you change first host and then create a cluster.
but i will check something and give you the answer where you can change the cluster communication.
