9.6 GRE Tunnel

GRE (Generic Routing Encapsulation) is a tunneling protocol used to create a virtual point-to-point link
between two networks to transport multicast, broadcast and non-IP packets like IPX. In the example
below, GRE establishes a private connection between the Zyxel Device (ZD) and remote router (RR)
over an IPv4 network. At the time of writing, the Zyxel Device only supports GRE tunneling in IPv4
networks.
Note: The GRE tunnel must also be configured on the remote router (RR).
