<p class=MsoNormal>I have a new Fedora 9 firewall I am setting up in front of
an Asterisk 1.4 box. I ported over all of my iptables rules..but now have
a strange problem: SOMETIMES, the audio is only 1-way (i.e. and RTP path
problem).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can someone offer a tip here? Since I have
conntrack_sip loaded on the firewall, do I need to:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>

</span></span><![endif]>Use SIP and RTP port forwarding & prerouting to my
asterisk box? (SIP clients are outside the LAN) – this is the way I
do it now<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Clearly something has changed with conntrack_sip or iptables
in the latest kernel...so I need to figure this out. Help!<o:p></o:p></p>
