NAT44 feature extends the usage of IPv4 by translating private IPv4 addresses that get allocated in the access network into public IPv4 addresses from a public IPv4 pool.

NAT44 is the NFWare vCGNAT operational mode for mapping each application flow on the customer side to the public IPv4 address and one of its TCP or UDP ports as identified by the combination of a private IPv4 address and a TCP or UDP port. vCGNAT multiplexes the addresses of many inside devices to a single outside address by mapping application flows.
