    enabled UFW, allowed rules - Nothign accesable anymore

    When configuring a firewall you typically don't use SOURCE port because applications on the client side will pick a random port. Selecting a DESTINATION port indicates what the client is talking to, which is where you configure your firewall rule.

    enabled UFW, allowed rules - Nothign accesable anymore

    Client machines use random ports to connect to a destination port. Remove the source port numbers.

    enabled UFW, allowed rules - Nothign accesable anymore

    That is not an rdp connection. Since the entry point is proxmox and not a direct connection to the console, it is more secure than opening up an rdp service to the web.

    Opening up remote desktop for a windows box on a public IP address is asking to get hacked.

    enabled UFW, allowed rules - Nothign accesable anymore

    Why wouldn't it be? Why would the fact that it's a VM change anything? If you have a public service hosted on a public IP, it is at risk. Period.

    enabled UFW, allowed rules - Nothign accesable anymore

    Anything with a public address is subject to attack. It doesn't matter what hypervisor the VM is running on or if it is running on physical hardware. I would trust a website running under Linux moreso than windows.

    Proxmox Web Gui - VMBR0 not active

    You can't pass your single public IP address to a VM and still have access to the host. You need to NAT in order for your VM to have internet access.

    Proxmox Web Gui - VMBR0 not active

    Is your VMBR0 on a public IP address or is it NATted behind a router? If it is public, you need NAT, or a router of some sort. If it is private ip address behind a router, why the F are you hiding your IP in your screenshot? In either case, it looks like it is the only device with an IP and...

    Ho do I enable multiple NICs on Proxmox node?

    create BRIDGES on the other nics. They do not need addresses on them, just create some VMBR devices with each one connected to an ETH device. Then use those bridges in your Sophos VM. You don't attach VMs directly to ETH devices, you attach them to VMBRs

    Open vSwitch VLAN must be done with Managed/Smartswitch?

    I don't understand how openvswitch would negate the need for tags to be passed through the switch in the correct manner.

    VM to VM connectivity

    Is there a reason you put an IP on that vmbr? It's not needed for an internal only vswitch

    Proxmox Backup

    NTFS isn't a file share protocol. It's a filesystem on a hard drive. The network share would be NFS or cifs/smb/samba

    VM Host rebooted by itself

    By default, there is nothing that will restart the server without your intervention. I would start with power supply. Test it. Make sure its good

    Proxmox install not recognizing mirror drives as the same

    When it comes to zfs, you should never let hardware raid get between zfs and the disks. Letting zfs control "half" of your raid config makes no sense. Zfs needs direct access to hardware (disks) in order to be beneficial and operate in a proper manner
