Hello Rafish,

 

Please try the below irule

 

when HTTP_REQUEST {

 

set low_host [string tolower [HTTP::host]]

 

if {(( $low_host starts_with "test1.technion.ac.il" ) || ( $low_host starts_with "test2.technion.ac.il" ) || ( $low_host starts_with "test3.technion.ac.il" ) || ( $low_host starts_with "test4.technion.ac.il" ) )&& ( [IP::addr [IP::client_addr] equals 10.10.10.10] )} {

 

HTTP::respond 404 content "Blocked by irule" log local0. "$low_host traffic has come from blocked subnet" }

 

}

 

I also got the same error and then I have given space between IP::addr and [IP::client_addr]. After that, irule was working fine. You can also given try by giving space between IP::addr and [IP::client_addr]
