It takes all of 2 seconds to restart IPtables so I'd suggest restarting IPtables period. If you are making a firewall change you have a reason for doing so and want to test it right way. So why chance that it automatically be re-read? If there is an error in my edits I want to see it right away and know about it right away.

I stated ever because the brand new features approach was once introduced that it could be plenty nearer and could be near all season. It will get much less and not more near because the season is going however it's going to nonetheless be nearer than earlier than. Right now Kyle Busch is the satisfactory restarter, however so much do not frequently have any issues on restarts. They appear to be pondering extra approximately ideas now.

It depends on what you mean by changed the rules. If you entered iptables commands to set rules then they're already active. If you set them in a config file somewhere, then you probably have to restart the service to apply them.
