Static IP Question

[sharingsunshine@]

Hello,

I have a new Plesk server and I need to implement a firewall. I have read the posts about APF and the iptables.

However, I am interested in the Plesk firewall due to ease of use, I am new to Linux so the Plesk approach seems easier for me.

My question, Is it more secure using the Plesk firewall to have a static IP and select the option "Allow from selected sources, deny from others"?

Or is there a better approach that will save the money used for the static IP and be just as secure?

Thanks in advance,

Randal
