-Two NB1600 connected through a GRE tunnel over the mobile interface.
+====== GRE Tunnel ======
+The Generic routing encapsulation (GRE) is a communication protocol used to establish a direct, point-to-point connection between network nodes. Being a simple and effective method of transporting data over a public network, such as the Internet, GRE lets two peers share data they wouldn’t be able to share over the public network itself.

+Bridge interface: LANX; the IP address on both sides must be in the same subnet. (e.g local=192.168.1.1 / remote=192.168.1.2)
