UFW and a Windows KVM with Virt-Manager (lemm.ee)

So, I finally ditched Windows... All except for my need for a VM to use some hardware that aren't supported in Windows.

I setup a Virtual Machine with Virt-Manager for a Windows VM but the network traffic is being blocked by UFW. If I disable UFW the Windows VM can pull an IP, which is static as is, and even after turning UFW back on, the network traffic is still allowed.

I am in need of some help with networking for the VM.

<interface type="network">
  <mac address="52:54:00:d7:8f:48"/>
  <source network="default" portid="d7ff3b1f-2c9b-4a62-b9e0-180855f14de7" bridge="virbr0"/>
  <target dev="vnet2"/>
  <model type="e1000e"/>
  <link state="up"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

This is the networking setup within Virt-Manager.

Any advice for getting network access on the VM?

It was able to get an IP, and I was able to get smb access, but for some reason still won't allow me to open a web browser and browse, or pull windows updates.

I may have to play around with what is allowed through UFW a bit yet.

Completely unrelated, but on my Wireguard/PiHole server I setup this weekend I did get a bit more familiarized with UFW and how that works a bit better. So with that fresh new experience for me I think I may have a few ideas on how to accomplish this.

And thank you again!

I will check again later tonight when I am back to my desktop.

Though I think another project I am going to do is instead of using a qcow2 image for my windows installation I am going to experiment with using a dedicated SSD for my windows installl to keep it out of my BTRFS snapshots, and hopefully have a bit better performance. As well as I might install my second GPU for GPU passthrough.
