Hi Sébastien There is a match module that may do what you want: "-m helper" with --helper argument that in wour case sould be "sip-xxxx" I believe I came across this in the iptables manual but never tested. Please let me know if it works for You. Best regards Michel 2007/8/23, Sebastien VECTEN <svecten@xxxxxxxxx>: > Hi, > > I tried to change the default port of sip_contrack and h323_conntrack in iptables. The problem is those conntrack are "hard compiled" in the kernel (not as module if not the command "modprobe ip_conntrack_sip port=xxxx" is the solution). > > I would like to know if its possible to change this port (without change kernel) when the conntrack is "hard compiled" and especially where?
