Configuring the Tunnel UDP Port

GRE encapsulation uses IP protocol 47 by default. However, GRE+UDP encapsulation is typically selected when tunneling traffic through NAT devices or in environments where UDP traversal is required for reliable connectivity.
Note: The Tunnel UDP Port parameter is set to 23233 by default for GRE+UDP tunnels. You may specify any UDP port value in the range from 1 through 65535, except 23232 which is reserved by the system and cannot be assigned.

Complete the following steps to specify the Tunnel UDP Port for all AP GRE+UDP tunnels.

  1. In the controller web UI, select Network > Wireless > AP Settings > General.
  2. In the AP GRE Tunnel Options section, enter the port number in Tunnel UDP Port.
  3. Click OK to save the setting or Cancel to return to the configure value.

You have specified the Tunnel UDP Port for all AP GRE+UDP tunnels.
