Changing RADIUS Port Numbers

If a remote server is listening for authentication or accounting requests on ports that are not the RADIUS defaults, you must configure the local server to forward messages to the correct port. The current RADIUS default ports are 1812 and 1813. Many older RADIUS servers listen for requests on ports 1645 and 1646.

Forwarding Requests to Alternate RADIUS Ports

Complete the following steps to forward requests to alternate RADIUS ports:

If you have not already configured the remote server, complete the steps listed in “Creating or Modifying a Proxy”. If the proxy configuration already exists, access it from the proxy screen.
In the Authentication relay port and Accounting relay port fields of the Proxy attributes screen, specify the alternate ports.
Click Create.
From the navigation tree, click Save Configuration.




	CAUTION: Clicking Save Configuration saves the entire server configuration (access devices, proxies, local realms, users, and server properties) to the servers you specify.
