GRE

The AirLink gateway can act as a Generic Routing Encapsulation (GRE)
endpoint, providing a means to encapsulate a wide variety of network layer
packets inside IP tunneling packets. With this feature you can reconfigure IP
architectures without worrying about connectivity. GRE creates a point-to-point
link between routers on an IP network.
To configure GRE:
1. In ACEmanager, go to VPN.
2. Select the VPN you want to configure (1, 2, 3, 4, or 5).
3. In the VPN Type field, select GRE. The screen expands to show the GRE
fields.
