If you can control both ends, I'd opt for OpenVPN. For the outside
addresses, it needs an UDP connection (standard port 1194 both ways).

L2tp is more complicated to set up.

You have still to determine whether you want transfer IP packets
or Ethernet frames. The former means less network traffic, but
it may limit some LAN protocols out.
