       xauthby
            When IKEv1 XAUTH support is available, set the method used by XAUTH to authenticate the user with
            IKEv1. The currently supported values are file (the default), pam or alwaysok. The password file is
            located at /etc/ipsec.d/passwd, and follows a syntax similar to the Apache htpasswd file, except an
            additional connection name argument (and optional static IP address) are also present:

                  username:password:conname:ipaddress


So you can add "special" users with static IP by adding:

 	myname:mypass:xauth-psk:10.3.0.49

Be careful not to assign static IP's from the addresspool= defined, or
you will get clashes.
