Hi, I am developing a module for a linux router. All the packets from LAN to WAN are natted. I am using linux 2.6.18.2 kernel. Hence for SIP/RTP packets from LAN to pass through I am using SIP Protocol Support of Netfilter by enabling CONFIG_IP_NF_SIP as module. The module I am developing needs to mark the SIP, RTP and RTCP packets with TOS/DSCP in IP Header and COS in the VLAN header. Can anyone please help me to achieve this task? Any pointers like documentation/suggestions to achieve this are greatly appreciated. Thank you very much for your help. Best Regards, marc
