Hello Nicholas!

 My main firewall/router/server has one Gigabit Ethernet port. That port is
 connected to a switch that supports VPN's and VPN trunking. Als Linux
 supports VPN and trunking, I use a trunk between the Server and teh Switch,
 the switch is trunked to a second smart switch.

 The second smart switch is located at a position that is convinient for
 a cable modem and a adsl router. The cable modem and the adsl router both have
 their on VPM to the main firewall/router/server.  A number of ports on both
 switches serve as endpoint for a third VPN that serves the LAN.

 So the single NIC on the server serves 3 networks, WAN1, WAN2 and LAN.

 At times the server/router functions as secondary router for IPv6. Up to four
 subnets can be requested from the ADSL router, one is assigned to the LAN.

 Apparently I did not transfer all the magic, that is needed for the IPv6
 subnet to the starup scripts. I recently had to shut the system down after
 an uptime of some 2 years, the IPv6 subnet did nor resurface. I will look into
 that again when time comes.

 I have used a Pi as a router in my motorhome. A power-Wifi or a 3g-dongle
 provide a Wan connection. A small usb Wifi then provides the in-vehicle Wifi.
 Of course the Lan port is also available. This setup can cope with the slow
 speeds of the wan connections. I intend to use a Pi3 next year, then the
 internal Wifi can give the in-vehicle lan.
