<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>I know this problem
comes up all the time so sorry to bring it up again but I can't seem to find the
answer in previous posts.</FONT></SPAN></DIV>

<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>I have my freeswitch
installation behind a DLink firewall so the freeswitch server is natted. I have
added what I believe are all the necessary rules to the firewall to handle SIP
correctly and the firewall isn't showing any blocked traffic when calls come in.
Calls are forwarded to my public ip address from my VOIP provider Voiptalk.
Here's the problem:</FONT></SPAN></DIV>

<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>Incoming calls are
successfully forwarded to the freeswitch server and
answered.</FONT></SPAN></DIV>
<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>I can hear the IVR
message played down the phone line so outgoing audio is ok.</FONT></SPAN></DIV>
<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>When I try
to send DTMF key presses from my phone none of these register on the
switch.</FONT></SPAN></DIV>
<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>When I hangup the
call the call hangup is also not picked up by the switch.</FONT></SPAN></DIV>

<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>I have followed the
auto-nat instrcutions and have verified that the switch correctly grabs and sets
the external ip address. I have also tried setting the external ip address
manually but without success.</FONT></SPAN></DIV>

<DIV><SPAN class=531040213-07102009><FONT size=2 face=Arial>Can anyone offer any
guidance as to what might be causing this problem or what I could try to resolve
it? I can post log/config snippets if that helps.</FONT></SPAN></DIV>
