Is it really necessary to run UFW behind my Gateway Router which already has Firewall/Port rules?In this example, I am discussing running UFW on an Internet Accessible (Linux) Server that is behind a Natted Firewall Gateway Router.Please be specific, don't just say yes because there are hackers out there! (Though that is valid answer)Is it just for internal protection? If so, I know I can trust my LAN, can I not run UFW?
