linux – How to add multiple IPs in one iptables command line? sudo iptables -A INPUT -p tcp –dport 22 ! -s 1.2.3.4 -j DROP

For example, My goal is Only allow allow only 1.2.3.4 and 11.22.33.44 to connect the ssh(port 22) of my server.

And I prefer this approach/command rather than others.

sudo iptables -A INPUT -p tcp --dport 22 ! -s 1.2.3.4 -j DROP

But I don’t know how to add another Allowed IP 11.22.33.44 in this command,

Could you give me a little bit help or tips?

Thanks.
