For those of you who understand how the internet works, each device has it’s own ip-address. The problem with this is that only 4 billion addresses are available, however more than 4 billion devices currently exist on the planet.
To overcome this many service providers have decided to implement CG-NAT. This is a technology in which a single ip address can span a large volume of customers or devices. However, is this new technology causing you issues?
We have recently come across issues with customers running older style PPTP VPNs within their business and reporting dropouts and connectivity problems.
Turning off CG-NAT may be the root cause of your problems.
