<div name="quoted-content">
<div>use tcpdump or similar to capture the traffic on the wire.
<div> </div>
<div>also get a siptrace from freeswitch console</div>
<div> </div>
<div>"sofia global siptrace on"</div>

<div>Hey Russel, thank you for your response.</div>
<div> </div>
<div>Nope, there're no NATs in my setup.</div>
<div> </div>
<div>I also should mention, that when I test my setup on FS machine with sipp:</div>
<div> </div>
<div>sipp -d 1 -r 1 -m 1 -i fs.ip.addr <a href="http://1.1.1.1:5060" target="_blank">1.1.1.1:5060</a></div>

<div> </div>
</div>
<div>the target sip server gets incoming call as it should do.</div>

<div style="font-family: Verdana;font-size: 12.0px;">
<div>Hi All,</div>
<div> </div>
<div>I want to register my FS machine (FreeSWITCH Version 1.6.0 - git 6762f14 2015-09-03 20:36:52Z 64bit - CentOS 6.7, selinux is disabled for debugging) as endpoint at another target SIP server (1.1.1.1). This is my gateways section:</div>
<div> </div>
<div>
<div> <gateway name="1111"><br/>
<param name="register" value="true"/><br/>
<param name="register-transport" value="udp"/><br/>
<param name="username" value="1111"/><br/>
<param name="realm" value="1.1.1.1"/><br/>
<param name="password" value='my_strong_pass"/><br/>
<param name="proxy" value="1.1.1.1"/><br/>
<param name="expire-seconds" value="90"/><br/>
</gateway></div>
<div> </div>
<div>The problem is - a target server at 1.1.1.1 receives absolutely no packets from my FS machine and I'm getting constant registration timeouts:</div>
<div> </div>
<div>
<div>2015-09-21 15:01:46.764466 [ERR] sofia_reg.c:2101 487020870 Registration Failed with status Request Timeout [408]. failure #1<br/>
2015-09-21 15:01:46.864501 [WARNING] sofia_reg.c:469 487020870 Failed Registration [408], setting retry to 30 seconds.</div>
</div>
<div> </div>
<div>Meanwhile, when I do UDP scan of port 5060 on 1.1.1.1 from FS machine, I see that port is opened:</div>
<div> </div>
<div>
<div>[root@srv]# nmap -sU -Pn -p U:5060 1.1.1.1</div>
<div>Starting Nmap 5.51 ( <a href="http://nmap.org" target="_blank">http://nmap.org</a> ) at 2015-09-21 15:28 EEST<br/>
Nmap scan report for 1.1.1.1<br/>
Host is up.<br/>
PORT STATE SERVICE<br/>
5060/udp open|filtered sip</div>
<div>Nmap done: 1 IP address (1 host up) scanned in 2.28 seconds<br/>
[root@srv]#</div>
<div> </div>
<div>When I filter out port 5060 on target machine 1.1.1.1 I see appropriate lines in the log showing filtered requests:</div>
<div> </div>
<div>
<div>Sep 21 10:39:57 sip kernel: DROP IN=eth0 OUT= MAC=00:16:3c SRC=2.2.2.2 DST=1.1.1.1 LEN=28 TOS=0x00 PREC=0x00 TTL=52 ID=10616 PROTO=UDP SPT=47229 DPT=5060 LEN=8<br/>
Sep 21 10:39:58 sip kernel: DROP IN=eth0 OUT= MAC=00:16:3c: SRC=2.2.2.2 DST=1.1.1.1 LEN=28 TOS=0x00 PREC=0x00 TTL=47 ID=23653 PROTO=UDP SPT=47230 DPT=5060 LEN=8</div>
<div> </div>
<div>Firewalls on both machines are off for debugging:</div>
<div> </div>
<div>
<div>[root@srv]# iptables -L -n<br/>
Chain INPUT (policy ACCEPT)<br/>
target prot opt source destination</div>
<div>Chain FORWARD (policy ACCEPT)<br/>
target prot opt source destination</div>
<div>Chain OUTPUT (policy ACCEPT)<br/>
target prot opt source destination<br/>
[root@srv]#</div>
</div>
<div> </div>
<div>I've spent many hours while investigating that quest but still have no ideas on what's happening. I'll highly appreciate if someone can point on where else I can look to resolve my issue.</div>
<div> </div>
<div>Thanks in advance</div>
