    Hello, how many networks do you need to match? 

    For allowing multiple client networks you'll need a data group. 

    See this example below - note that "getfield" returns a string so I'm changing the format to IP address using IP::addr .

     

    when HTTP_REQUEST {
      if {[string tolower [HTTP::uri]] starts_with "/restricted1" }{
    
       if { [IP::addr [getfield [IP::client_addr] "%" 1] equals "10.2.2.0/24"]}{
           #this is a sample with a static client network
           return
        } elseif { [class match [getfield [IP::client_addr] "%" 1] equals datagroup_allowed_networks] } {
        #when you have multiple subnet to match, then it is recommended to use data-group created as Address (IP) type. 
           return
        } else {
          HTTP::redirect "https://demo.com/not-allowed"
        }
    }
