Yes, 

I was just writing an answer when the vpn suggestion came up. I think using Tink would be a nice approach: http://tinc-vpn.org/

You can also build a meshed VPN with tink, so you get failover as well. Tink does automatically restart, the virtual nics can be bridged to inside networks if needed.


Kind regards,
