Basically, there was an asymmetry in the order the two filters were called, because the code in ip_input.c called IPFILTER before entering the IPFW code, and ip_output.c did the same, while it should have called first IPFW then IPFILTER. (beware, it might have been the opposite WRT what was first in which function, I don't remember exactly). Does your new code take this ordering issue into account? I suppose it would be nice to be able to control the order filters are processed: I may like IPFW to be 'wrapping' IPFILTER (that is, called before it during input, and after it during output), while others might prefer the opposite. And anyway, am I right the filter list should be traversed in opposite directions during input versus output (maybe it's already so).
