Plans

• Hypervisor's linux bridges work as L2 switch
  • br0 is completely L2 switch (LinkLocalAddressing=no)
  • br1 has ip address for hypervisor itself, but basically works as L2 switch whitch can deal with VLAN tags; id=1,10
• Firewall's port (wan) works as Gateway which can conduct NAT
• Firewall's port (clients) works as trunk port which can deal with VLAN tags; id=1,10,20
• Firewall's port
  • client, id = 1
  • server, id = 10
  • user, id = 20
  • wg0
