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.

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.
