<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have my Asterisk behind a NAT router, but now it
is configured to put that specific computer in DMZ (directly exposed to
Internet).</FONT></DIV>
<DIV><FONT face=Arial size=2>I intend to disable this and to open just the used
ports.</FONT></DIV>
<DIV><FONT face=Arial size=2>There is a list of TCP/UDP ports usd by Asterisk in
order to connect to the outside world?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>One more question: When a call is established
between an internal SIP phone (in LAN) and a phone from another place outside my
router/firewall, using both the same codec (no conversion)... the call is still
routed through the PBX or the PBX is used only for signaling and then a
direct connection between the two phones is established?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I ask this because if the audio stream is passed
through the PBX then there is no need to open other ports on the firewall
for the internal phones.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
