I use ipfw2. Please make it possible (using sysctl or any other mean) to disable M_SKIP_FIREWALL for such packets (I suppose 'unreach' rules are affected too). I DO need to process ALL outgoing packets. For exapmle, I must use 'ipfw fwd' (to implement policy routing) for the packets with source IP like this.
