Thank you, nice tutorial, you could of used some systax complete to speed up the process instead of typing everything by hand. but it was nice

what is the difference between NAT and SNAT?

Can i use that in paid vps ? To my router ?

Why is it better to have a tool like firewall-cmd than just using iptables and maybe write a little bash script for it? I am not a CentOS user though.
