changes that is present only when you make changes. For example, the system limit of 32 PDM sessions represents a limit of
64 HTTPS connections.

using PAT is the translation limit (256,000), not the higher connection limit. To use the connection limit, you need to use
NAT, which allows multiple connections using the same translation session.
