Goal: Host machine running Virtual Machine Manager to have guest vm router on the LAN.
Host Ubuntu 22.04 Desktop 192.168.1.120 pinging VM router pfSense 192.168.1.1 error: Destination Host Unreachable.
The problem might be between netplan and libvirtd?
VMM automatically creates a bridge virbr0 and I don't know how to ignore it and use my created bridges NIC0-br0 and NIC1-br1.
Bridges I created:
NetworkManager configuration file:
Routes:
Not sure if there's an iptables issue?
