Hi all I'm trying to prioritize the out going SIP related traffic from my desktop computer. I tried: iptables -t mangle -A POSTROUTING \ -m helper --helper sip -m state --state ESTABLISHED,RELATED \ -j ... It simply doesn't detect SIP related traffic! I'm using Linux kernel 2.6.11.9, iptables 1.3.5 and sip-conntrack-nat from patch-o-matic-ng-20060502. I have enabled the Mangling, SIP support in the kernel (as built-in, not as a module). Have I missed something? any ideas? Thanks Kind regards Sagara __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
