Twice Static NAT Overview
Twice static NAT translates both the source and destination IP addresses. An addresses is translated with a one-to-one static mapping to an address in a pool. Port mapping is not performed.
The original private domain host source address is translated to a public source address.
The destination address is translated to the IPv4 address of a private server. This redirects traffic destined to a virtual host (identified by the original destination IP address) to the real host (identified by the translated destination IP address).
Allows hosts in the private network to connect with the external domain, while hiding the private network.
Hides a private network
Allows external traffic to communicate with a private host without revealing the host’s private IP address
Does not require port mapping
