You're free to restart anything you want, of course. Reboot the whole machine every time you change anything, that way you'll be sure. I am not stopping you, and in some cases it can be useful to make absolutely certain. I only pointed out that "ufw reload" is not necessary to make "ufw allow/deny/delete" take effect. Multiple people might not have known that, judging from the upvotes I got. And now I find I have to justify myself. Is that being "pedantic"? Am I the one "rushing"? I don't see a reason why reload should be "good practice". If ufw or your config is buggy, it is very possible for the rules not to apply at next boot, when iptables is reset. If this is critical, reboot and do a test connection.
