[Serusers] Problem with the gw-pstn.cfg

Dear Friends and Supporters! I have a problem with the permissions module. I use the gw-pstn.cfg as my ser.cfg. I install asterisk on the same server. It works with any other ser.cfg. However, after I copy the gw-pstn.cfg to ser.cfg and correct the ip address as well as the realm. However I never let me register. It's alware return the true to if (!is_uri_host_local()) { if (!is_from_local() || allow_trusted()) { route(4); route(1); } else { sl_send_reply("403", "Forbidden"); break; }; With the error message on my Xten is 403", "Forbidden" Eventhough I have set the perminssions.allow to ALL : ALL Is any ideal Thanks for your help and supports!
