Re: [SR-Users] Problem with t_relay() and VPN tunnel

Hi, I have two SIP servers, *A* and *B*, connected each other though a OPENVPN tunnel. The server *B* needs to t_relay() every SIP message containing the method MESSAGE to the server *A* but these messages never reach destination. I have tested the tunnel connectivity and works fine. I wrote a Perl script (located in *B*) that sends SIP MESSAGES to Kamailio (located in *A*) trying to figure out what is happening but these messages are received by *A* and processed correctly but when *B* does the same from Kamailio, it is never received. Here is the route part of kamailio.cfg in *B*: Observation: ($rU == "1004") result is *true* / if(is_method("MESSAGE")) { if($rU == "1004") { xlog("L_INFO","En 1004"); rewritehost("10.8.0.1"); if (!t_relay()) xlog("L_INFO","MIO Error en t_relay"); t_reply("200", "Ok"); xlog("L_INFO","MIO despues rewrite"); exit; } ...../ The perl script that WORKS: /$msg = 'MESSAGE sip:1004@192.168.1.2:5060 <http://sip:1004@192.168.1.2:5060> SIP/2.0 Via: SIP/2.0/UDP 192.168.1.2 From: "2002" <sip:2002@192.168.1.2 <mailto:sip%3A2002@192.168.1.2>>;tag=1837944796 To: <sip:1004@192.168.1.2 <mailto:sip%3A1004@192.168.1.2>> Call-ID: 19722852989(a)192.168.1.2 <mailto:19722852989@192.168.1.2> CSeq: 15773 MESSAGE Contact: <sip:2002@//*PublicIP-protected*//:5060> Max-Forwards: 29 User-Agent: DBL Content-Type: text/plain Content-Length: 34 +595981[*protected*] hello from kamailio '; use IO::Socket; my $sock = IO::Socket::INET->new( Proto=>'udp', PeerHost=>'192.168.2.102', PeerPort=>'5060'); print "Sending msg $msg\n"; $sock->send($msg) or die "error sending $!\n"; /Please help!
