Memory footprint (RAM): Turbo CG-NAT requires at least 2GB of RAM. Default capabilities are automatically adjusted to the amount of RAM available.
The maximum numbers for NAT entries, CPEs (users), conntracks (sessions), blocks and block sizes are defined in the configuration. These capabilities can be adjusted to adapt to the amount of memory available in the system.
The following table shows a list of different capability combinations and the corresponding memory requirement. This is empirical and may have to be tuned according to your use case.
Max conntracks Max nat entries Max cpe Max blocks Required memory 1M 1M 10K 80K 5 GB 2M 2M 20K 80K 6 GB 4M 4M 20K 80K 8 GB 8M 8M 20K 80K 12 GB 16M 16M 20K 80K 24 GB 30M 30M 20K 80K 32 GB
Fast path limits configuration to tune these capabilities.
CPU: Turbo CG-NAT requires at least 2 CPU cores.
- Storage: Turbo CG-NAT requires at least 1GB of storage space; 8GB are recommended to manage several images and store configuration and log files.
