Hi Zeus,
Yes, my SER is running behind netscreen firewall + NAT and has a public IP address (202.129.171.223). I have enable all outoing port and limited incoming port (5004 and 5005). Which is running in the company I work for.
The UAs is running at home which is behind my NETGEAR router, if I do a port fowarding on my NETGEAR router to forward 5004 to my grandstream (129.168.0.3) then I can hear the voice. But I can't hear the echo.
I have try to call home from the office (X-lite to grandstream), but only one direction can hear, the UA at home can hear the voice but UA in my office can't the the voice.
Like you said, properly is the voice is block by the NAT. But I give you another sinareo, if I turn on the port forwarding, I call talk to another UA which has public IP address (connected to another ADSL line).
Please advice, C.K

C.K.,
I notice that your SER is behind a NAT (I assume), not just a firewall. From my experience, SER will only function properly if it has a public IP. PAT or NAT for SER will not work. I don't know how you get around it. Are you running it in your lab? Forgive me but I would say that it will not work in a real world environment.
Regards,
Zeus
