As of lately (a week or two, using 7.3 and the problem persists after upgrading to 7.4), when I migrate a LXC from a node (e.g. proxmox1) to another node (e.g. proxmox4), the LXC cannot connect/ping to, or be connected/pinged from, any LXC but those in the same, new node.
When I migrate...
I have recently set-up a Proxmox VE cluster with 2 HPE DL380e Gen. 8.
I’m now looking at the best way to have a segmented virtual network that could span the cluster nodes, so to ensure VMs on the same LAN can communicate to each other regardless of the host where they reside.
