You host a web server in your DMZ that’s configured with your private IP addressing scheme. Which of these would you need to configure in your router to allow access to this server from your public IP address?
A) Destination NAT
B) Proxy ARP
C) Static routes
D) IPv6
E) Maybe it’s time to remove the blink tag from your home page
The answer: A) Destination NAT
Network Address Translation allows you to change the destination IP address as traffic flows through an OSI layer 3 device like a router or firewall. Using Destination NAT, you can convert the public IP address to your private IP address and successfully route the traffic into your DMZ.
