Add timeout controls for SNAT_Pool class

Open walterk82 opened this issue 3 years ago • 4 comments

Describe the solution you'd like

SNAT_Pool class does not support configuring TCP/UDP/IP timeout values. These then use the BIG-IP default "indefinite".

See https://support.f5.com/csp/article/K7606

Important: Using an indefinite idle timeout can lead to resource exhaustion if connections are not shut down gracefully. This is especially true for TCP-based communication. In most cases, F5 recommends that you set the idle timeout to a small-as-possible finite value.

Describe alternatives you've considered

SNAT must be configured outside of AS3

Additional context

Timeout values need to be configurable so that tmm resource exhaustion does not occur.

Can you please provide an example of the tmsh configuration you want?
