6WIND Turbo CG-NAT® is a high performance, ready-to-use vRouter or virtual router, software network appliance. It is deployed bare metal or in virtual machines on commercial-off-the-shelf (COTS) servers as a replacement for legacy router hardware. Carrier Grade NAT (CG-NAT), also known as Large Scale NAT, (LSN) shares an outside IP address among multiple inside local (private) IP addresses. 6WIND’s Turbo CG-NAT brings additional features to 6WIND’s vRouter family for the ability to use a pool of public IP addresses instead of one, limit resource usage per user and add transparent translation schemes.
