Ipitables command

in iptables i wrote some rule. Is it possible to start/stop/restart iptables?

for example with command: iptables stop

Thank you

iptables is a command it’s not a service that can start/stop/restart

Yes you are right, but if I write: iptables -t nat -A PREROUTING -p tcp --dport 22 -j DNAT --to-destination

Immediatly after this rule work fine. So I presume that there is a system that permitt to work. How Can I stop this system?

Thank you

yes the rule is getting activate asap. You just can remove it. There is nothing to stop. You would need to remove the rule if not needed anymore.
