Bridged mode not receiving inbound connections/pings

With PVE 4.4, I've got some Windows VM's in bridged mode, and they're properly getting a DHCP address from our network (in fact, one is getting the one assigned to its MAC address). They're able to make outbound connections to the network (eg. surfing the web, etc).

The problem is that they can't receive inbound connections. I'm unable to contact them through SMB/CIFS, plain ol' netcat (with the VM listening with netcat on port 8000), no replies from pings, and, curiously, nmap reports that the host is up, but filtered:

Starting Nmap 7.40 ( https://nmap.org ) at 2017-05-11 09:49 PDT
Nmap scan report for XXXXXXXXXXX (###.###.##.##)
Host is up (-0.20s latency).
All 1000 scanned ports on XXXXXXXXXXX (###.###.##.##) are filtered
MAC Address: XX:XX:XX:XX:XX:XX (Unknown)

Nmap done: 1 IP address (1 host up) scanned in 21.51 seconds

I've checked the firewall settings (in PVE, not Windows) for the VM, and the firewall is off.

Anybody know what the deal is, here?
 
is the windows firewall off ?
to make sure you're not blocking from inside the VM, start a netcat client inside the VM and bind to your 8000 port using the external IP address of the VM
