Carrier Grade NAT and IPv4 to IPv6 Migration
Challenges faced by the Internet provider
Operators need to connect new customers to the network and provide them with IP addresses. According to the requirements of the law in many countries, it is necessary to collect the NAT logs. Service providers have to consider the deployment and integration of IPv6 into the network and extend the use of existing IPv4 addresses, and we are here to help.
The best solution is a smooth transition of the entire infrastructure to IPv6 support and the creation of a temporary hybrid scheme. We suggest VAS Experts CG-NAT as part of this strategy.
Benefits of CG-NAT from VAS Experts
Effectively uses limited IPv4 address space
NAT significantly expands the network capabilities. Since the IPv4 address limit is almost exhausted today, it is necessary to use the available addresses effectively and maintain the smooth operation of the network.
Saves capital network costs
We use standard x86 servers as a platform. It is inexpensive and cross-functional, there are quite a large number of manufacturers in different price categories on the market, repair and maintenance of such servers is also not a problem.
Increases security
By default, NAT discards connections initiated from the Internet, which makes it possible to protect users from scanning and hacking devices.
Provides a high level of connection
Carrier-level NAT provides transparent operation of P2P protocols (torrents, games) using Full Cone technology and application-level gateways (ALG) for client applications. Also, with the help of redundancy mechanisms, high availability for trouble-free operation is achieved.
Running in a virtual environment
Stingray SG software functions can be used in virtual environments; KVM, VMware, Hyper-V hypervisors are supported.
SaaS and flexible payment options
We offer different payment options, including the Pay-as-you-Grow model: you pay only for what you use, and the amount of the monthly payment depends on the number of active subscribers served. This pattern allows the operator to optimize capital expenditures when launching the solution.
Extend IPv4 Connectivity
The addresses of the fourth version protocol, which is responsible for establishing a connection between network nodes (computers, servers, mobile devices, etc.), are currently insufficient: more than 4.3 billion devices are already used in the world.
Our NAT product suits Internet Service Providers of any size. Installed on a standard x86 server, it is flexible, affordable, and easy to scale. This solution will give you time to prepare your network for IPv6 implementation and still have transparent and reliable network address translation.
IPv6 Implementation
IPv6 is the next-generation protocol. Its main advantage is the increased address size from 32 to 128 bits, which gives an almost inexhaustible supply of unique IP addresses. Carrier-Grade NAT technology assumes using up to 64,000 ports on 1 public address.
However, 3000 ports for TCP and UDP connections per subscriber are enough for comfortable operation. You get the optimal coefficient up to 1:10 (10 private IPs are translated to 1 public IP). This is the best practice due to the fact that many services (such as mail, video, search, and others) use protection against BotNet attacks based on IP addresses. Therefore, the smaller the number of addresses, the lower the risk of blocking or enabling captcha.

Migration from IPv4 to IPv6
We recommend using the CG-NAT solution of the Stingray platform as part of smooth migration to IPv6 strategy and support for Dual Stack IPv4/IPv6 so that NAT v4 and v6 would work simultaneously. The Application Layer Gateways (ALGs) ensure that multi-channel applications connect normally to the entire Internet, no matter which IP version is used.
Features
Supports IPv6 and Dual Stack IPv4/IPv6 for compatibility: NAT v4 and v6 work simultaneously.
Built-in IPSec for encrypting data packets.
Allows flexible and centralized management of the whole set of external and internal addresses.
Determines the availability of TCP- and UDP-ports (vital for improving port utilization and protection against DDoS attacks).
With the QoE module, it is possible to identify subscribers with BotNet-infected devices.
With the Graphical User Interface, it is convenient to configure and work with log files to meet the requirements of the regulator.
