im always trying to make sure im not putting my own foot in my own mouth either, so there you go 🙂
There used to be an option in 2.4 called ‘CONFIG_FILTER’, that may be enabled in 2.6 by default because its no longer an option, however it doesnt seem to apply to iptables. As the option itself in the description says its ‘ok to leave disabled’ since unless your a programmer you wont be utilizing it anyways, lol.
