I don't think this is possible out-of-the-box, but with use of iRules and iRulesLX you can build about anything. So yes, this is possible. What would be the use case for this?

    Hi Niels,

    The use case is one of the customer is accessing the application over UDP to our LB VIP whereas the LB VIP and backend appication servers are listening on TCP port.

     

    So we want the incoming request to LB on UDP needs to be changed to TCP when the new session intiated to the backend server.

     

    so that I'm thinking to have VIP listening on UDP port whereas the backend server listening on TCP port.

     

    Could you please help me to know how we can achive this using irules?

     

    Regards,

    Thiyagu

      Sorry, but I can't help you with this. This sounds like a bad plan. I think you should go for a solution where both the client and server are using the same protocol.
