font-family:Arial'>I have an Asterisk PBX behind a ‘manually-built’
IPCHAINS firewall machine. Can anyone tell me what I need to allow/build
QOS packet rewrites through this simple NAT barrier? What do I need to
pass to IPCHAINS to let QOS out to the next outside network hop? </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I ask this, because I have been getting intermittent jitter
from my provider (TELIAX), and since it seems near-impossible to verify the
source of the latency, I want to make sure I have all my ‘Ts crossed and I’s
dotted’ before I blame something external for my issues.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

for jitter, packet loss, etc, and still be able to determine what the potential
culprit is for the problem?</span></font></p>
