What is NAT and how does it work?

Network Address Translation (NAT) conserves IP addresses by enabling private IP networks using unregistered IP addresses to go online. Before NAT forwards packets between the networks it connects, it translates the private internal network addresses into legal, globally unique addresses.

How does NAT Pat make network management easier?

NAT Advantages:

  1. By managing and reusing the IP addresses the NAT can prevent the exhaustion of the IPV4 addressing scheme.
  2. It provisions the security to the private network from the outside world by maintaining the secrecy of source and destination IP address from the external network.

Can I disable NAT on my router?

You can’t actually ‘disable’ NAT, it’s a feature you either use or don’t use. The most common reason for asking this question is that users want their public (routable) IP address to be allocated to a client PC (or other device) behind the router rather than that device having a private (NAT) IP address.
