ZTNA Gateway on alternate Hypervisor

Hey all,

We're using ZTNA wherever we can, normally with Sophos firewalls. Works great. We have one situation where we're hosting servers for clients, so we need to use the VM gateway as only one tenant can use the firewall. We have had mixed results on the VM coming online properly. Though I'm working with support on it, I figured I'd ask here...

Has anyone reliably setup VMs in Proxmox to communicate? I have one online (on some beefy stuff) and a couple have worked *sort of* elsewhere. I have others that are basically just a NUC with Proxmox on it hosting the VMs. These ones seem to get stuck waiting on the K3s service to start. but if I backup and restore the same VM with the same ISO, it works. All in Proxmox.

Weird.
