The IP addresses are assigned to devices, not to humans. The device can be a computer, mobile, tablet, or any other machine that is part of the TCP/IP-based network. Therefore, the Internet Protocol (IP) address is defined as a unique numeric string identifier separated by the periods and is allocated to each device on the internet. Moreover, address refers to the unique numeric string identifier that links all your internet activities. The protocol means the guidelines or the rules and regulations to govern the connectivity on the internet. So the real question arises, what is the IP address? " What is my IP address" was searched millions of times on Google. You cannot ignore the importance of the IP address. You cannot check your email, your social media updates, even cannot perform any internet activity without an IP address. When you visit any website, how these websites come to know that you are the person that is requesting a specific URL.

Have you ever thought about how the internet comes to know that you want that exact website and, more importantly, how the website comes to know that you are the person who requested that specific URL to open in your system browser? When you write any valid URL address in your browser bar, instantly, you land on the exact landing page that you requested.

Rdr pass inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080įirst two lines after echo are the entries that were already there. What interests us is actual entries so ommit first two info lines. My output was like: No ALTQ support in kernel First find what entries do you already have with: To extend solution from answer, I created two super-basic Shell Scripts to enable or disable redirecting without compromising already existing entries in pf. If you want to forward across different interfaces you have to enable this in /etc/nf: .forwarding=1
