Cluster over subnet mask 255.255.0.0

[j.io]

Hi all,

I have 2 remote locations with Proxmox, one being 10.0.3.2 and one being 10.1.3.2. The connection is handled by a VPN tunnel. When I tried to create a cluster to be able to migrate VMs and manage the "cluster" from a single web interface, I learned, that only subnet masks 255.255.255.0 are supported for clustering.

Is there a particular reason for that? How would you deal with that situation then?

Thanks!

I would use IPv6 (and probably not a VPN tunnel for cluster communication...).

How does that solve the problem?
