Thank Samir,

 

I will look into, but i found very strange thing. I have two F5 pair

 

10200 - 12.0.0 software code - Same SNAT pool configuration working fine without filling ephemeral ports

10350 - 13.1.0.8 software code - Same SNAT pool configuration **not** working and filling ephemeral ports

 

I will try your logic to set 900s timeout but if you see i am using XMPP persistent TCP connection, there is no re-use of any connection if client make connection it stay connected for lifetime (with keep-alive etc)

Raise case with F5 support. They will help here.
