Ethernet controller pass-through successful, but internet connection failed

[netnoob]

I have successfully done Ethernet controller passthough, with the spaceinvader video, using the vfio-pci.ids method. But i cannot get connected to the internet inside the VM, using the passthough NIC and i am not sure what the source of the problem is.

 

I am running an untangle firewall with a 4-port NIC and and unraid server with an onboard nic, and an extra 2-port NIC.  Here is my setup:

 

UNtangle:

• port 1: External
• port 2: internal
• Port 3: Unraid + docker (VPN)
• Port 4: Unraid VM (NO VPN)

 

Unraid:

• eth0: connected to Untangle network port 3
• eth1 from 2-port nic: connected to Untangle network Port 4
