VPN > GRE > GRE Tunnels

On this window, you configure the settings for GRE Generic Routing Encapsulation tunnels.

 

  • Add GRE Tunnel — Click to add a GRE tunnel.

  • Tunnel Name — Specify a name for the tunnel.

  • Enable this tunnel — Select to enable the tunnel; clear to disable the tunnel.

  • Tunnel IP Address — Type the tunnel's IP address in dotted-decimal format.  This address should be on an unused subnet that is not configured on the module or its host switch.

  • Firewall Zone Association — Select a zone from the list to add the tunnel IP to the zone.

  • Local IP Address — Type the tunnel's local IP address in dotted-decimal format.

  • Remote IP Address — Type the tunnel's remote IP address in dotted-decimal format.

  • Add Traffic Selector — Click to specify the destination of the tunnel traffic.

  • IP Address — Type the IP address in dotted-decimal format. Type 0.0.0.0 to select all traffic.

 

You cannot configure a default gateway if you have configured a GRE tunnel with 0.0.0.0/0 in the traffic selector and vice-versa.

 

  • Subnet Mask — Type the subnet mask in dotted-decimal format. Type 0.0.0.0 if you typed 0.0.0.0 in the IP Address field.

 

When you click OK, you save your changes to the running-config only. If you reboot the module without saving your changes, you will lose those changes. To save your running-config to the startup-config, click Save in the upper-right corner of the Web browser interface.

 

After you configure the GRE tunnel, you must configure firewall access policies to permit the tunnel traffic.
