I was thinking of writing a iptables bash script.... Let's say I mess something up or do not cover every security aspect (which is impossible to do anyway
). Would flushing the current rules be working against me? As in, will be writing a sub-par script and flushing current (default) rulesets be to my disadvantage? Basically how good are the default iptable rules and would flushing them be a BAD idea?
(note: Im running slackware 9.1 if that makes any diff)
