Extend IPv4 connectivity and migrate seamlessly to IPv6
The NFWare Virtual Carrier Grade NAT (CGNAT) is a high-performance software-based solution for transparent address and protocol translation. It allows service providers of any size to extend their IPv4 networks quickly and enables a smooth transition to IPv6.
NFWare CGNAT works as a Virtual Machine on top of standard x86 server and supports NAT44 and DS-Lite modes.
Carrier Grade NAT (CGN or CGNAT), also known as Large Scale NAT (LSN) is a way of solving the problem of the limited supply of IP addresses available in IPv4's 32-bit address space. It uses translator devices embedded in the operator's network to change private network addresses into public IPv4 addresses. This enables the sharing of small pools of public addresses among multiple end sites, thus greatly expanding the capacity of the existing network.
