Block Traffic To App Mac

FreeBlock

I'm trying to determine the best way to block traffic from my mac to a specific IP address on my internal network.
From what I can tell I could potentially setup something in IPFW to block all outbound traffic to a specific ip address on the mac. Or I could try to setup an ACL on my switch to block the communication. However I can't find enough information on either one to know for sure if either will work for what I need.
I need to make sure that the mac will not be able to communicate on any port with a specific ip address. including UDP broadcasts that the mac does. Can someone help point me in the right direction as to which solution to use, if either of those will work. and if they won't does anyone have other ideas?
Both the mac, and the other device have static ip addresses, so I don't have to worry about ips changing on me at all.
Thanks for any help you can give.

Sep 07, 2018  Little Snitch is a firewall application and, as you may know, your Mac has a built-in firewall that you can turn on and use to quietly block unauthorized incoming network connections. So why buy a separate app if you already have something built-in? The answer is simple: Little Snitch does more than just block or allow incoming network connections.
