Hi Guy,

You missed parenthesizes in if sentence. The correct version of your irule version is :

when HTTP_REQUEST { 
if { ([string tolower [HTTP::host]] starts_with "test1.technion.ac.il" || [HTTP::host] starts_with "test2.technion.ac.il" || [HTTP::host] starts_with "test3.technion.ac.il" || [HTTP::host] starts_with "test4.technion.ac.il") and [IP::addr[IP::remote_addr] not equals 10.10.10.10/255.255.255.255] }
{ 
HTTP::respond 404 "Not Found" "Connection" "close" log local0. "This Connetion blocked By iRule My-iRule" 
} 
}
