I have all the DNAT rule set Any > TeamSpeak Service Ports > WAN, Destination Translates to TeamSpeak VM. No issues there, as far as I can tell. There is nothing in the logs that indicates whether something has connected, or is trying to connect, there are no other firewalls active, unless Proxmox Firewall is automatic, I read it wasn't.
The Proxmox networking looks like this with Eth1 being the physical WAN port (Connects to Modem), and eth2 the physical LAN port (Connects to Physical switch). These are both assigned to the Sophos VM. The VM bridges correspond to the physical port, 0 >1, 1 > 2, 2 >3, 3 > 4.
Everything else in Sophos is fresh out of the box, there haven't been any changes other than what the setup wizard changes. TeamSpeak here is just an example, as all other services perform the same way. Additionally, I've gone through all of the Rulz.
