GRE Tunnel GRE tunnels allow LAN broadcast traffic of the gateway to pass over the Internet and receive by the remote LAN hosts. While creating a GRE tunnel, a unique IP address should identify the GRE tunnel endpoint. It will be referenced in the other gateway's static route as the Gateway IP address. The Remote end-address in the GRE tunnel configuration page is the WAN IP address of the other endpoint gateway. Once the tunnel is established, a static route on the gateway can be made using the interface of the configured GRE tunnel. The destination IP address of the static route is the remote LAN subnet. The route's gateway IP address will be the GRE tunnel IP of the terminating gateway (the same gateway that manages the remote LAN subnet). Once these two steps are completed, the traffic can flow between the configured remote LAN subnets via the GRE tunnel. The fields displayed in the Configuration table are as follows: Field Name Interface GRE tunnel IP Description It displays the name of the GRE tunnel. It displays the interface with which this tunnel is created. It displays the IP address of this endpoint. 125

GRE Tunnel
GRE tunnels allow LAN broadcast traffic of the gateway to pass over the Internet and receive by the remote LAN hosts. While creating a GRE
tunnel, a unique IP address should identify the GRE tunnel endpoint. It will be referenced in the other gateway’s static route as the Gateway IP
address. The Remote end-address in the GRE tunnel configuration page is the WAN IP address of the other endpoint gateway.
Once the tunnel is established, a static route on the gateway can be made using the interface of the configured GRE tunnel. The destination IP
address of the static route is the remote LAN subnet. The route’s gateway IP address will be the GRE tunnel IP of the terminating gateway (the
same gateway that manages the remote LAN subnet). Once these two steps are completed, the traffic can flow between the configured remote
LAN subnets via the GRE tunnel.
