NAT (Network Address Translation) is the remapping of one IP address space into another by modifying the network address information in the IP header of the packets while they are in transit across a router. Use NAT to quickly assign new IP addresses to all devices in a network when you need to move the network or replace an internet service provider. Typically, configuring NAT on a router allows you to use a unique IP address to represent all devices in your local network while they are communicating with the internet.
On the NAT Rules page, the Cloud Services Portal displays the following information for each NAT rule:
