[Serusers] mediaproxy register problem

[Sönmez Güneş]

Hi everybody,

I setup ser 0.8.14 with mysql support on fedora core 2. And two UA
could connect over SER successfully.

I give a static IP to my SIP PROXY and followed ONSIP instructions
about mediaproxy. But I could not register UAC's behind NAT.

begining of my route block:

       if (method=="INVITE" && client_nat_test("3")) {
               # INSERT YOUR IP ADDRESS HERE
               record_route_preset("PROXY_IP:5060;nat=yes");
       } else if (method!="REGISTER") {
               record_route();
       };

       # -----------------------------------------------------------------
       # Call Tear Down Section
       # -----------------------------------------------------------------
       if (method=="BYE" || method=="CANCEL") {
               end_media_session();
       };

       # -----------------------------------------------------------------
       # Loose Route Section
       # -----------------------------------------------------------------
       if (loose_route()) {

               if (has_totag() && (method=="INVITE" || method=="ACK")) {

                       if (client_nat_test("3") ||
search("^Route:.*;nat=yes")) {
                               setflag(6);
                               use_media_proxy();
                       };
               };

               route(1);
               break;
       };

my register block:

       # -----------------------------------------------------------------
       # REGISTER Message Handler
       # ----------------------------------------------------------------

       sl_send_reply("100", "Trying");

       if (!search("^Contact:\ +\*") && client_nat_test("7")) {
               setflag(6);
               fix_nated_contact();
               force_rport();
       };

       if (!www_authorize("PROXY_IP","subscriber")) {
               www_challenge("PROXY_IP","0");
               break;
       };

       if (!check_to()) {
               sl_send_reply("401", "Unauthorized");
               break;
       };

       consume_credentials();

       if (!save("location")) {
               sl_reply_error();
       };

invite block: 

       # -----------------------------------------------------------------
       # CANCEL and INVITE Message Handler
       # -----------------------------------------------------------------

       if (client_nat_test("3")) {
               setflag(7);
               force_rport();
               fix_nated_contact();
       };

       lookup("aliases");
       if (uri!=myself) {
               route(1);
               break;
       };

       if (!lookup("location")) {
               sl_send_reply("404", "User Not Found");
               break;
       };

       if (method=="CANCEL") {
               route(1);
               break;
       };

       if (!proxy_authorize("PROXY_IP","subscriber")) {
               proxy_challenge("PROXY_IP","0");
               break;
       } else if (!check_from()) {
               sl_send_reply("403", "Use From=ID");
               break;
       };

       consume_credentials();

       if (isflagset(6) || isflagset(7)) {
               use_media_proxy();
       };

       route(1);

Any help would be appreciated...
