Hello, I am having probs with the fix_nated_register() function, I still see the private IP, even thought the nat_uac_test(31) shows the user behind a NAT

This is the REGISTER section in kamailio.cfg:

if (method=="REGISTER") {
                        xlog("L_INFO","mylog: starting to process REGISTER.Info: [$au].\n");
                        if (!www_authorize("", "subscriber")) {
                                xlog("L_INFO","mylog: REGISTER came without auth, sending challenge.\n");
                                www_challenge("", "0");
                                exit;
                        };
                        if (nat_uac_test("31")){
                                xlog("L_INFO","mylog: Device behind NAT.\n");
                                fix_nated_register();
                                force_rport();
                        }
                        save("location");
                        xlog("L_INFO","mylog: save-location successful.\n");
                        exit;


this is the debug log [level 6], it shows the via with a public IP

and this is how the AOR is stored in the location db [ private IP]

Am I missing something?

Thanks in advance
