<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Reading about CBQ on internet i can say "I dont understand well"  ;)</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">So anyone that has a good background can help me out with this simple question ?</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">I just want priorize my UDP packets to always has 90% of my link when use a VOIP</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">connection with asterisk.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">My asterisk run in the same machine then my firewall.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">How then can i :</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">1 - Mark the packets with iptables then i will know TCP and UDP packets then come in and out</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">2 - Use CBQ to put a prio=1 in the UDP Packets then i will always know that when a VOIP conn start will</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">always have the best rate of my link.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">I think i know how mark the packets with the Iptables.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">iptables -t mangle -A PREROUTING -p tcp -j MARK --set-mark 9000</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">iptables -t mangle -A PREROUTING -p udp -j MARK --set-mark 9002</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">and</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">iptables -t mangle -A OUTPUT -p tcp -j MARK --set-mark 9001</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">iptables -t mangle -A OUTPUT -p udp -j MARK --set-mark 9003</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">I think that i mark all UDP and TCP packets.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">So i just need use a CBQ RUle (Now it's the worst) </SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Honestly i dont know ..</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">So let's see.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">DEVICE=eth0,10Mbit,1Mbit</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">RATE=112Kbit</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">WEIGHT=1Kbit</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">MARK=9000</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">etc etc</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">I use an 256kbits(Down) - 128Kbits(Up) ADSL connection</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Then i have PPP0 and my eth1 for my internet net.</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Just need put the best priority to all UDP Packets forcing the rest of services like</SPAN></p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">SMTP/POP3./HTTP etc that use TCP in the low priority</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Can anyone help me ? Because i think my Voip has a poor quality because this (Heavy use of mail and http services).</SPAN></p>
<p> </p>
<p><SPAN style="font-family:'Tahoma';font-size:10pt;">Thanks alot for helping out.</SPAN></p>
