Troubleshooting Tip: ZTNA unable to added mappedport on Access proxy setting

When trying to edit the mappedport on the current setting of access proxy with mappedport will encounter:

config firewall access-proxy

    edit "Server"

        config api-gateway

            edit 1

                config realservers

                    edit 1

                        set mappedport 1 2 3 4 5 6 7 8 9 10 11 12 13 

end

Can not set port ranges over 16
Command fail. Return code -1

Even if the number of mappedport is under 16, the error 'Can not set port ranges over 16' can still be seen. The system only accepts 8 mappedport ranges when using CLI.

The issue is aware of, and the current workaround is:

• Making the change on the GUI instead of the CLI.
• Delete the object and create a new one with a new mappedport.

The issue is resolved on FortiOS v7.6.3 above.
