Fortinet FortiGuard Web Filtering Service Port Changes

Changing Fortinet FortiGuard Web Filtering Service Port in CLI

Fortinet FortiGuard Web Filter uses HTTPS on port 443 by default. To change the port or protocol, follow the CLI configuration steps below.

Step 1: Disable FortiGuard Anycast

Before modifying the transport protocol and port, you must disable FortiGuard Anycast. Run the following command:

config system fortiguard set fortiguard-anycast disable

Step 2: Configure the Protocol and Port

Once FortiGuard Anycast is disabled, you can specify the transport protocol and port as needed. For example, to use UDP with port 53, use the following command:

config system fortiguard set protocol udp 
config system fortiguard set port 53 

This configuration allows FortiGuard services to use UDP on port 53 instead of the default HTTPS (port 443).
