Re: cleaning up my firewall script...
I think you mean -P OUTPUT(or whatever) DROP(This has to be a built-in target). If you do want to
append a blank rule to be a sudo policy, then I say go with the first as it's more flexable. Keep
inmind that any other appended(-A) rule will not be called.
I put up a script that helps sort throught all this -A and -I trash.
