Carrier Grade NAT vRouter Software Appliance

6WIND Turbo CG-NAT is a high performance, ready-to-use vRouter software network appliance, to be deployed in bare metal environments or as a virtual machine. With 10 Gbps per core of performance, 6WIND Turbo CG-NAT provides the performance of hardware networking equipment with the ease of deployment and flexibility of software.

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.
