[OpenSIPS-Users] b2bua top hiding behind NAT

[Alex]

Hello,

Not only do I need force messages from internet to lan through
udp:10.130.23:5070 but also I need send messages from lan
(udp:10.130.23:5070) to internet (udp:10.130.23:5060). So I make rule with
if and $socket_in .
But Messages (Updates, reInvites) and replies go directly between LAN and
10.130.23:5060 thought.
All messages (input, output, replies) must go between two sockets
10.130.23:5070 <-> 10.130.23:5060 .
                b2b_server_new("server1",$avp(b2b_hdrs),
$avp(b2b_hdr_bodies));
                if ($socket_in == "udp:10.130.0.23:5070") {
                        force_send_socket("udp:10.130.23:5060");
                } else {
                        force_send_socket("udp:10.130.23:5070");
                }
                b2b_client_new("Unistar","sip:09876543322 at provider.com
","sip:provider","test","sip:1234567 at 1.1.1.1");
                #force_send_socket("udp:10.130.23:5070");
                b2b_init_request("top hiding");
                exit;

But Updates go from 5060 directly to lan. I made a screenshot you can see
