+ (FAQ 77) Shorewall is eating my Asterisk egress traffic! + + 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. + + Answer (requires Shorewall 4.0.6 or + later): If your kernel version is 2.6.20 or + earlier:rmmod ip_nat_sip +rmmod ip_conntrack_sipThen change the DONT_LOAD specification + in your shorewall.conf to:DONT_LOAD=ip_nat_sip,ip_conntrack_sipIf + your kernel version is 2.6.21 or later:rmmod nf_nat_sip +rmmod nf_conntrack_sipThen change the DONT_LOAD specification + in your shorewall.conf to:DONT_LOAD=nf_nat_sip,nf_conntrack_sip +
