    How to enable "Use Client Source IP Address” in RADIUS manually via the configuration file rather than using the RADIUS admin console.



    In the affected version(s) stated above, the ability to enable "Use Client Source IP Address” as per the documentation is missing from the user interface in the RADIUS admin console.


    Additionally it may be desired to make this change for multiple RADIUS clients such as instances where an upgrade has been made from a much earlier version of RADIUS (e.g. 2.3.X) where "Client Source IP Address" is used as the NAS Identifier by default, but RADIUS 20.12.07 uses NAS-IP-Address by default.



    1. Stop the RADIUS service.
    2. Open the RADIUS configuration file in a text editor.  Default location is:
      C:\Program Files\SecureAuth Corporation\SecureAuth IdP RADIUS Agent\bin\conf\
    3. Search for the following text:
    4. Replace with:
    5. Repeat for any remaining instances as required.  Each instance relates to an individual RADIUS client.
    6. Save the file
    7. Start the RADIUS server
    8. RADIUS clients will now be identified by their actual IP rather than the NAS-IP-Address RADIUS attribute embedded in the RADIUS packet.
