Help installing vm router OPNsense on KVM

[eiger3790]

Having some trouble pinging the VM guest OPNsense from the host VMM.
Here's my diagram/topology of the setup:
Host machine runs Ubuntu 22.04 Desktop and Virtual Machine Manager 4.0.0.
ISP router is bridged and Internet traffic is via NIC0 to the host machine.
2 physical NICs:
NIC0=WAN=enp3s0=a8:a1:59:6e:1f:8b=br0=0a:d4:78:1f:cd:41=vtnet0=52:54:00:c9:2f:af.
NIC1=LAN=enp2s0=1c:61:b4:6d:3B:4f=br1=d2:da:46:a2:b2:3e=vtnet1=52:54:00:ad:30:31.
I setup bridges, which show connected:

I edited the host Ubuntu's Network Manager so the host's LAN will ping the guest OPNsense router:

Host connections show no IP address 192.168.1.120?
