I was one of those who VTCed, and though I can't remember my choice of reason it's clear it wasn't "product recommendation". Here's what I think now.
Firstly, it's a "please fix my iptables" question that doesn't post the complete ruleset (
iptables -L -n -v); those are damned from minute one, in my eyes. While a quick update can rescue such a question, after seven years it seemed unlikely in this case.I dislike such questions anyway, as the solution details are often highly specific to the ruleset in question (I miss the old "too narrow" close reason); to make them scale to others, an answer has to be written that becomes a general primer on iptables, and that is too broad / a request for learning materials.
The question, being unanswerable in its present form (no live ruleset) was still attracting noob-quality "here's what worked for me" answers seven years after it was asked. The author clearly has no intention of cleaning up behind him/herself, so closing it was pretty much a mercy killing in that it stopped any more ill-thought-out answers from being posted.
Without endorsing Womble's attitude to hand-written iptables rulesets (I do those all the time, but then I actually did write the book on it :) I would also like to see the question burninated. But closing it is nearly as good.
