By default, LTM should not change the source port of client requests unless the source port is already in use on the serverside to the same destination IP. CMP can also affect the source port selection.

 

 

If this is failing for you constantly, I'd open a case with F5 Support. They'll be able to help you capture tcpdumps and review your configuration.
