Forcepoint GRE Guide
Forcepoint GRE connectivity can be used to forward traffic from your network's edge devices to the Forcepoint cloud service over a GRE tunnel. This guide introduces the basics of Forcepoint's GRE solution, and provides information on planning and deploying GRE in your network.
Introduction to the Forcepoint GRE solution
Generic Routing Encapsulation (GRE) is a tunneling protocol used to encapsulate and route data via a virtual point-to-point connection. Forcepoint GRE supports manual end user authentication and transparent identification via NTLM. Transparent authentication allows users to browse the Internet without explicitly providing logon credentials.
Typical uses for the GRE service include providing Forcepoint Web Security Cloud/Hybrid protection for:

Benefits
Using GRE to forward traffic to the cloud service can provide a number of benefits. These include:
*
*

Capacity planning
Forcepoint GRE supports up to 5Gbps throughput per tunnel and 1,000,000 concurrent connections.
By default, tunnels are configured for 200Mbps throughput. Customers requiring more than the default can submit a request to Forcepoint Technical Support.
Supported devices
Most devices that support GRE tunneling, and that are able to forward port 80 and port 443 traffic to the tunnel, can be used with the service. Forcepoint recommends using the latest firmware for your device.
Redundancy and failover
By default, two Forcepoint data centers are provided for GRE connectivity. Forcepoint strongly recommends configuring your device to fail over to a second data center cluster to achieve geographic redundancy.
