Also note that you'll want to lock connections to certain NICs using MAC
addresses. That way the connection that you mark "only use this
connection for resources on its network" will always get assigned to the
same NIC and your network setup will be stable. You can do that by
typing in the NIC's MAC address in the "Wired" tab for that connection,
in the "MAC Address" field.
