Using the Loopback Interface to simulate a DMZ
Posted on 2003-03-12
I need a detailed explanation of what the loopback interface is and how it works. If my IP address is 192.168.2.2 and the loopback interface is 127.0.0.1 how to they relate to each other? I know that both will allow me to view web pages on my machine with web services running but I dont know how they differ or how they compare or how they really work.
I also need to simulate a DMZ/lan environment and setup a simple firewall with the loopback interface as part of the DMZ and the assigned IP as part of the protected lan environment. Can you explain this concept to me? It is worth alot of points if you can.
