Irule : Filtering source ip and redirecting it to specific node and disabling the snat

Im relatively new in creating an iRule . We have a requirement where we need to filter a specific host ip and when it hits the vip, it will be redirected to a specific node . Additional requirement is that the irule should disable the snat once the source ip hits the specific node. I dont know how feasible are these . Thanks in advance

    Hi iamjepoy2k16,

    an iRule to overwrite the server-side node address and SNAT settings for a specific client IP will look like this...

    when CLIENT_ACCEPTED {
    if { [IP::client_addr] eq "1.1.1.1" } then {
        node 2.2.2.2
        snat none
    }
}

    Note: If you use route domains you have to suffix the IPs with your route domain id (e.g. 

    1.1.1.1%2
    )

    Cheers, Kai
