CG-NAT is a solution that implements the functions of network address translation in the network of a telecom operator. The system is aimed to solve the problem of shortage of global IPv4 addresses while maintaining the existing telecom infrastructure.

NFWare vCGNAT is a carrier-grade NAT function that allows transparent IP addresses and protocols by giving one IP address to several clients. It thus solves the problem of IPv4 addresses exhaustion, working entirely in a virtual environment without the need for specialized, dedicated hardware. It provides the high-quality IP addresses and throughput speed that telcos demand in order to deliver the best customer experience.
