FastL4 doesn´t work with Snat pool

We had to configure a performance layer 4 vip and it only works with automap. We would need to use it with a snat pool because of the amount of connections. Any recomendation? Is there any sol that says that with that type of vs you have to use only automap? Below the virtual server config:

 

ltm virtual test-L4 { destination x.x.x.x:http ip-protocol tcp mask 255.255.255.255 pool test-L4-pool profiles { fastL4 { } } source 0.0.0.0/0 source-address-translation { type automap }

 

Thanks in advance and regards.

    SNAT should still work in a fastL4 profile, though it will demote PVA acceleration to 'assisted' mode for platforms that have a PVA. What makes you say it doesn't work with fastL4 ?

     

    Alternatively, you could add another floating self IP to that vlan for automap to use

    Ian, it doesn´t work with snat pool in version 11.5.3, but it works int 12. I don´t know if it´s a bug or a known issue of the version. Thanks for your answer.

     

    Regards.

      I'm not aware of any such bug. I recommend you open a support case with F5 to investigate the situation
