Hair-pinning, also known as NAT loopback, is a technique where a machine accesses another machine on the LAN or DMZ via an external network. There is port forwarding on the rou Without Hairpin NAT, your router would not understand this request because it expects requests for the public IP address to come from outside the network. I am not a networking professional and I am open to any criticism on how to implement it in a better … We will describe the behavior and possible configurations of a somewhat specific situation. Overview Readers will learn how to configure Hairpin NAT (Network Address Translation) to work alongside Destination NAT. Source NAT If you want to hide your local devices behind your public IP address received from the ISP, you should configure the source network address translation (masquerading) feature of the MikroTik router. Hairpin NAT solves this problem by allowing the router to recognize that, although the request is being made to a public IP, it needs to be routed to a device on the local network.
