How to open port for specific IP?

Using Mac OS, how to open port (3005) to specific IP, so only that IP can access it, using CLI and firewall? Doing on Linux Ubuntu server I am using the UFW service which is simple. How to do the same thing using MacOS with Nodejs app using express?

Mac OS X 10.6 (and earlier) came with IPFW, a port of FreeBSD’s stateful firewall[1]. IPFW was deprecated in OS X 10.7, and was completely removed in OS X 10.10; it was replaced with PF. PF (Packet Filter) is OpenBSD’s system for filtering TCP/IP traffic and doing Network Address Translation[2]. PF in OS X, however, appears to be based on the FreeBSD port of PF[3], but with some notable additions (see below). Like FreeBSD 9.X and later, OS X appears to use the same version of PF as OpenBSD 4.5. Note that the latest OpenBSD version is 5.6 (as of January 2015);and the configuration syntax for PF changed around 4.6/4.7.
