I think that would be a good idea; I'm not aware of anything like this for the netfilter lists themselves, and I think a good starting point would be a copy of "Jeff's Rules" as posted on Monday, together with Aldo's recommendation to read Oskar's tutorial before posting (and preferably, before trying to configure netfilter). I think something like this would go well on http://www.netfilter.org/contact.html Antony. -- 90% of network problems are routing problems. 9 of the remaining 10% are routing problems in the other direction. The remaining 1% might be something else, but check the routing anyway. Please reply to the list; please don't CC me.
