How to setup the UDP VS to receive and respond to the request

We have the requirement where in we want to configure the VS to receive the request and pass on to pool servers. The pool server will process the request and respond back to client. also the client ip should be visible to servers.

    Hi,

     

    1. if the client ip should be visible to servers, F5 self IP (or floating if in HA pair) must be configured as default gateway of servers.
    2. The VS must be configured with protocol UDP.
    3. create the pool and assign it as VS default pool.

    Hi,

    the following configuration is wrong:

    source-address-translation {
    type automap
}
translate-address disabled
translate-port disabled

    the configuration must be:

    source-address-translation {type none}
translate-address enabled
translate-port enabled

    Source address translation is to hide client IP... you don't want it so you need to disable it

    translate-address is to replace VS address by the server address... do not disable it if it is not a "forwarding" virtual server (for outgoing connections)
