I've recently come back to UnRaid.  I'm trying to move from ESXi for my VMs.  I have installed a new Windows 11 VM, but I'm having issues with it on the Bridged network.  I've tried the virtio, virtnet, and Intel network drivers.  Oddly, they all will get a DHCP address assigned to them, but I can't ping the default gateway.  I can ping the IP address of the UnRaid host.  

 

If I change the network source from br0 to virbr0, it works fine, but it's on a different subnet (I'm guessing, NAT'ed behind my Unraid box).  I am planning to put a VM in a DMZ, and for that, I'll definitely want it to be directly on that network for port forwarding from the Internet.

 

If I look at the ARP table on the VM, the only thing I have on my local subnet is the broadcast address and my UnRaid host.  

 

I'm on the latest UnRAID, 6.12.10.  I'm using a Unifi switch and a Firewalla as my gateway.

 

And idea what's wrong here? 

Oh, and as another Datapoint, I had a Fedora VM up and running on the same subnet, and it worked fine.

I think when Fedora was working was before I had added a VLAN to the br interface.  I reinstalled Fedora and it was behaving the same as Win11.  I have a somewhat unusual config.  I ended up placing these on a different VLAN (which is bridged to the default VLAN - don't ask, I'm not sure I could adequately explain it), and they both came up and are working as expected.
