I'm setting the filter on the PREROUTING chain in the mangle table and no packets are registered? I have a suspicion that the checksums in the packets are incorrect, so would this cause it, and any work arounds (so I can just match ip addresses for e.g. and then drop the packet). Hmm I suppose if the checksum is wrong you can't depend on anything, but I'm just surprised iptraf can log them which netfilter can't. cheers, P=E1draig.
