VNS3 NATe is a virtual NAT gateway which is mostly used by cloud service providers. The best part is that it provides the functionalities of traditional NAT gateways in a virtual environment and offers better security. One can use it through the AWS marketplace and not just as a NAT gateway, but it also has firewall functionalities. On the other hand, it is commercially much cheaper than traditional NAT. The flexibility in terms of scalability is also much better than traditional providers. Review collected by and hosted on G2.com.
I really don't find anything big to dislike it at first sight, but there are some functional issues which sometimes irritate the administrator. However, I am sure these issues are manageable and won't create much dissatisfaction. Review collected by and hosted on G2.com.
