ASM hide support id external access

Yes you can do this via an iRule as follows. Anything not in the 10.10.10 network will get the custom page.

when ASM_REQUEST_BLOCKING {
    if { ! ([IP::client_addr] starts_with "10.10.10.")} {
       set response "REQUEST BLOCKEDPlease contact support at 1800 234 234 for assistance"
       ASM::payload replace 0 [ASM::payload length] ""
       ASM::payload replace 0 0 $response
       set asm_payload_length [ASM::payload length]
    }
}
when HTTP_RESPONSE_RELEASE {
   if {[info exists asm_payload_length]} {
       HTTP::header replace Content-Length $asm_payload_length
   }
}
