Host machine running VMM to ping VM router and vice versa

The challenge is to make the host machine with the VMM, ping the VM router and vice versa.

The only difference to a previously working network build exactly like this, is the hypervisor/VMM was not KVM/Qemu/Virt manager.

My network has:

1 pyhsical router bridged.

2 physical wired NICs for WAN and LAN.

1 host machine Debian based OS, running hypervisor/VMM KVM/Qemu/Virt manager.

1 VM router OPNsense (FreeBSD based).

Please see the attachment for the network topology (note the VM router's install default IP address is [login to view URL], I will change this to [login to view URL] when I have GUI access to the VM router's settings).

The VM router is pinging the Internet and LAN devices.

Here's 5 different /etc/network/interfaces configurations I've tried on the host machine, in attempt to connect the host's interface to the vm router:

1. ----------------------------------------------------------------------------------

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

auto lo

iface lo inet loopback

auto enp3s0

iface enp3s0 inet static

address [login to view URL]

gateway [login to view URL]

2. --------------------------------------------------------------------------

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

auto lo

iface lo inet loopback

auto enp2s0

iface enp2s0 inet static

address [login to view URL]

gateway [login to view URL]

3. --------------------------------------------------------------------------

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

auto lo

iface lo inet loopback

auto macvtap1@enp2s0

iface macvtap1@enp2s0 inet static

address [login to view URL]

gateway [login to view URL]

4. -------------------------------------------------------------------------

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

auto lo

iface lo inet loopback

auto macvtap1

iface macvtap1 inet static

address [login to view URL]

gateway [login to view URL]

5. -------------------------------------------------------------------------

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

auto lo

iface lo inet loopback

auto vtnet1

iface vtnet1 inet static

address [login to view URL]

gateway [login to view URL]
