Hello Paco,
Client X-Lite:
IP: 192.168.1.2 (public address 81.39.220.5)
Listen SIP port: 5060
Listen RTP port: 8000
Server: Openser 1.0 with Media Proxy
IP: 147.83.197.39
Config in opernser.cfg
If i try to register with a UAC (X-Lite or K-Phone) with symmetric NAT
scenario. Opernser server doesn't answer the client to 5060 port, as i need.
X-Lite Diagnostic LOG is client_messages.txt
Client timed out without receiving any server messages.
This is a tcpdump on clients side:

On the server this is the tcpdump:
17:42:23.904035 IP 81.39.220.5.10145 > 147.83.197.39.5060: SIP, length: 448
You can see here that the NAT device is changing the source port from
5060 to 10145, which is the port used by Openser to send the reply.
Openser is doing fine while your NAT device is doing wrong because it
keeps the external rewriten source port when sending the packet to the
internal side of the NAT (see the second line of the above tcpdump
trace).
Which NAT device/router are you using?. Are you forwarding ports from
the external to the internal side at the NAT device?.

What's wrong?
It's necessary to use a STUN server?
Why can't register?
Why openser doesn't reply to 5060 port? My client it's only reachable in
this.
Can anyone help me?
Anyone have a OpenSer config working?
Thanks in advance
