    Hi Preet_pk 

    If site/url is not working after mapping pool directly to the vServer then the issue is something else. 

    Can you verify below configurations ?

    1. SNAT settings on the vServer. If backend server's default gateway is not F5 then make sure to enable SNAT settings. You can set it to AUTOMAP.

    2. Is your pool showing up on the F5? Check if you have correct routing on the F5 to reach backend server.

    Once this is sorted. then you can test the iRule.

Hi,

Thanks for the details. Issue is sorted out - issue was due to missing route to backend application server subnet in F5.
