Currently I'm building a 'gateway-machine' that should get some rather complicated (considering my knowledge of the networking code) jobs done. (NAT on multiple interfaces, transparent proxying, etc.) My former natd/ipfw-setups were quite simple. But now I'm in need of more detailed information concerning: - at which stages/times the filter engine sees each packet - whether a packet already translated by the natd, carries all the 'additional' information (e.x. direction, incoming interface, etc) further on - etc. etc. Yes, ... I've read the obviously available (man-page, READMEs, etc.) documentation thoroughly.
