Documentation For Firewall

please anyone can give me a refrence to Documentation procedures for changing firewall

I didn't quite understand what you're asking

Could you be more specific, do you want best practices for migrating to a new firewall?

what is with people asking questions and never coming back for answers at this site? there are tons of posts like this. The first day I was on here, I got a PM asking for help, I politely replied that I would try, and never got a response about what they even wanted... crazy..

Yeah unfortunately a lot of people want to solve a problem, so they google for something, spam a few thousand forums with the same question, and then often find a way to fix it.. then they don't even bother going back and posting the solution for other people to benefit from..

It really irritates me.
