    Here's an iRule to accomplish it. 

    
when HTTP_REQUEST {
   if { [HTTP::host] eq "www.mysite.com" and [HTTP::uri] starts_with "/admin" and ![class match [IP::client_addr] eq inside_addresses] } {
     discard }}

    This requires that you create an address-type "datagroup" containing the IPs you want to allow. Let me know if you have any issues.

    hi chris

     

     

    thank you for your kind replay

     

     

     

    let's assume that 192.168.1.0/24 is the subnet which i want them to access the link and discard evrey thing else who we could write this ?

     

     

    and what if the link is not like www.mysite.com/admin and it's like www.admin.mysite.com ?

     

     

    regards

    This should work. 

    
when HTTP_REQUEST {
   if { [HTTP::host] eq "www.admin.mysite.com" and ![IP::addr [IP::client_addr]/24 eq 192.168.1.0] } {
     discard }}

    Let me know if it doesn't.
