Re: [Serusers] NAT-Issue in onsip.org's GettingStarted?

Hi, While experimenting with the example config nat-mediaproxy.5.0.cfg of onsip.org's GettingStarted document I discovered a problem with NAT handling. Don't blame me if I'm completely wrong, but here is what happens and how it is solved: I've two phones behind the same NAT (address of phone A is a:5060 and that of phone B is b:5060, the NAT device has ip c) contacting a SER with a public IP. If A makes a call, it's NATed to c:5060, SER responds with 407 to c:5060, and it's correctly forwarded to a:5060. If B makes a call, it's NATed to c:1025, but SER responds to c:5060 too, so B never gets the reply. The original config looks like this: 181 # ---------------------------------------------------------- 182 # INVITE Message Handler 183 # ---------------------------------------------------------- 184 185 if (!proxy_authorize("","subscriber")) { 186 proxy_challenge("","0"); 187 break; 188 } else if (!check_from()) { 189 sl_send_reply("403", "Use From=ID"); 190 break; 191 }; 192 193 consume_credentials(); 194 195 if (client_nat_test("3")) { 196 setflag(7); 197 force_rport(); 198 fix_nated_contact(); 199 }; So the autorization is done before NAT is handled, and I think this is the problem. Because if I move the lines 195-199 before 185, everything works as expected. Could anyone please be so kind and check that?
