    Hi Sunnyman,

    This will work;

    if { [IP::addr [IP::client_addr] equals 1.1.1.1] || [IP::addr [IP::client_addr] equals 1.1.1.2} { 
    SNAT with 1.1.1.100
    snatpool VM_SNAT_POOL_1_1_1_100
} elseif { [IP::addr [IP::client_addr] equals 1.1.1.11] || [IP::addr [IP::client_addr] equals 1.1.1.12} { 
    SNAT with 1.1.1.100
    snatpool VM_SNAT_POOL_1_1_1_200
}

    But that's not a very scalable way of doing it if your list is going to grow. If it's going to grow then use an address datagroup, with values snatpool names, which you can use like this

    snatpool [class match -value [IP::remote_addr] equals dg_sunnyman_snatpools]

    or more correctly;

    set snatpool [class match -value [IP::remote_addr] equals dg_sunnyman_snatpools]
if {$snatpool ne "") {
    snatpool $snatpool
 }

Hi joanna, i have one another question: i have one VS, i want to do SNAT through different SNAT Pool List upon the client source IP address. For example, if the source ip address of client is 1.1.1.1/24 or 1.1.1.2/24, VS should changes the source ip address of outgoing packet to 1.1.1.100, and if the source ip address of client is 1.1.1.11/24 or 1.1.1.12/24, VS should changes the source ip address of outgoing packet to 1.1.1.200. I've checked it with below script, but it didn't work! Am i wrong? Can you help me? Is there any need to use of HTTP_REQUEST or some other methods???

when HTTP_REQUEST {

switch -glob [IP::client_addr] {

  "1.1.1.1" - 
  "1.1.1.2" {
     SNAT with 1.1.1.100
     snatpool VM_SNAT_POOL_1_1_1_100
  }

  "1.1.1.11" - 
  "1.1.1.12" {
    SNAT with 1.1.1.200
    snatpool VM_SNAT_POOL_1_1_1_200
  }

} }
