    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
 }

Thanks Joanna, i've checked your new solution, but "LB_SELECTED" was not supported. My F5 load-balancer OS version is 10.2.4, but it doesn't support it. Also, i think that the URL i used in L7 is important, because it should be present on destination server, and in my scenario there is no domain name (URL) on the destination server. So, it's important to fill URL with true value. Now, how can i rewrite the URL "http:/abc.com/ukm/" on server 2.2.2.2 , to URL "http://1.1.1.1:8080/xyz/" on server 1.1.1.1 ?
