Final answer:
The number of SNAT ports allocated to a Load Balancer's public IP can vary and is typically large enough to support thousands of concurrent connections. It depends on the specific cloud provider or network appliance and customization might be necessary for high traffic scenarios.
Step-by-step explanation:
When configuring Source Network Address Translation (SNAT) for a Load Balancer, the number of SNAT ports allocated to a Load Balancer's public IP address can vary based on the specific cloud provider or the network appliance being used.
By default, cloud providers like AWS and Azure allocate a pre-defined range of ports for SNAT that can be used by virtual machines or services behind the Load Balancer.
This range is typically large enough to support thousands of concurrent connections. However, for scenarios requiring a high number of outbound connections, understanding and sometimes customizing the SNAT port range is essential to avoid port exhaustion, which could lead to dropped connections or timeouts.
