Can't Ping or RDP into VM.

I am having trouble with RDPing into my windows 8.1 VM.  I am set up for a public bridge and I have internet, network access on the guest VM, and ping other computers from the guest.  But I can not ping my VM from another computer or RDP into it.

 

Here is a copy of my XML

Here is a screen shot of my unRAID network settings.

I figured out the problem, some how my network was set to public instead of private.  Once I noticed that the firewall allowed private networks and not public I made the switch and I was able to ping my VM and then RDP into it.  I don't know how the network was set to public I know I didn't set it up that way, maybe the net network drivers on the virtio-win-0.1.96.iso had something to do with it because I was never asked what kind of network I was connected too.

I had the same thing happen. It wasn't the virtIO drivers specifically, it was the fact the the network was changed and when I first setup Windows I set it to default any new networks to public.
