Hello,

You can use list directly in the irule as shown in the example below : 

when RULE_INIT {
    set static::ipaddress ["10.1.1.1" "10.1.1.2" "10.1.1.3"]
}

when HTTP_REQUEST {
    if { [lsearch -glob $static::ipaddress "[IP::client_addr]"] != -1 } {
        pool mypool
    } else {
        pool default_pool
    }
}
