GRE

Configure GRE tunnels to establish connectivity between nodes and external devices

Trustgrid supports configuring GRE tunnels that can be used to establish connectivity to any appliance that supports the GRE protocol. A GRE tunnel interface is created which can then be attached to an interface on a node. VRFs can then be used to control the flow of traffic and how it should appear on the network.

Configure GRE Tunnel

On a Trustgrid Node navigate to Tunnels under the Network Menu, select Add Tunnel, and then select GRE
