Network

network:
  version: 2
  renderer: networkd
  ethernets:
    eth1:
      addresses:
      - 192.168.10.10/24
    eth2:
      addresses:
      - 10.8.220.224/24

eth2 is bridged over the intranet. The local area network cannot be connected with ping. Computers with virtual machines installed with IP, can communicate with ping.
