<title>(FAQ 77) Shorewall is eating my Asterisk egress traffic!</title>
<para>Somehow, my firewall config is causing a one-way audio problem in
Asterisk. If a person calls into the PBX, they cannot hear me speaking,
but I can hear them. If I plug the Asterisk server directly into the
router, bypassing the firewall, the problem goes away.</para>
<para><emphasis role="bold">Answer (requires Shorewall 4.0.6 or
later):</emphasis> If your kernel version is 2.6.20 or
earlier:<programlisting>rmmod ip_nat_sip
rmmod ip_conntrack_sip</programlisting>Then change the DONT_LOAD specification
in your shorewall.conf to:<programlisting>DONT_LOAD=ip_nat_sip,ip_conntrack_sip</programlisting>If
your kernel version is 2.6.21 or later:<programlisting>rmmod nf_nat_sip
