CGNAT (Carrier Grade NAT), also known as Large Scale NAT, is the next level for NAT implementations.
CGNAT allows organizations to deliver transparent IPv4 connectivity and a proper user experience. Carriers can assign local (private) IPv4 addresses on their access network and use a centralized device to manage addresses translation for the global (public) Internet.
CGNAT Type |
Flexible Deployment |
| Deterministic - Allocation of a fixed number of TCP/UDP ports per Public IPv4. Bulk - Ports Dynamic Allocation, allocating blocks with pre-defined fixed size. Dynamic - Allocation is made according to application needs, without the use of pre-defined blocks. Full Cone Nat NAT feature that allows the connection of an external host to service type such as P2P, Games, VPN, etc. |
-High Availability -In-band and out-of-band management -Link Aggregation -Customized log export Multi Tenant- Infrastructure virtualization through V-Sys e V-Route. Advanced Features- Application Control - Attack Defense - IP Reputation filter - Botnet C&C Prevention |
The topology at the right figure shows a use case where end users, particularly home users, are configured with private network addresses that are converted to public IPV4 addresses by the CGNAT device present on the carrier network , allowing the sharing of small sets of public addresses among many end user.
