Hi Andy,

 

 

I wouldn't suggest setting any idle timeout to indefinite as unclean closes will leave stale connections in the connection table until a restart.

 

 

I'd guess it's a SNAT timeout that you're hitting if you've already checked the protocol profile idle timeout. It could also be the timeout on the persistence profile. I assume if you're using a fastL4 profile that you're using source address persistence. You might try creating a custom persistence profile with the idle timeout set to something like 3600 seconds and retest.

 

 

SOL7606 has details on the various session timeouts:
