Hi, I've read this:

 

https://support.f5.com/csp/article/K6017

 

If the connection matches a virtual server and automap SNAT object, the system uses the idle timeout specified in the protocol profile. For more information about idle session timeouts, refer to K7606: Overview of BIG-IP LTM idle session timeouts.

 

and then the K7606 mentioned above:

 

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

 

With the idle timeout set to Indefinite, the BIG-IP system internally limits UDP and IP SNAT translation idle timeout periods to a maximum of 300 seconds.

 

So, which timeout win if I've an UDP VS configured with both, UDP profile set to 900 sec. and SNAT automap ?

 

Thank you
