Then you can use a class match function along with a data group to define your external IP ranges you want redirected.

Something like this:

when HTTP_REQUEST {
   if { ([HTTP::host] equals "www.example.fr") and [class match [IP::client_addr] equals "specific_external_client_range_data_group"] } {
       HTTP::redirect "www.example.fr/ckpartner"
       log local0. "Client IP [IP::client_addr] has been redirected"
     }
}

To create a data group you can use tmsh create /ltm data-group...

I'd also advise you to look into LTM policies as they might be more efficient.

Please, test it first 🙂

Thanks for your help ,

 

My requirement is currently working with below Irule but I would like to add Datagroup to below Irule so that I can filter more external IP's

Could you please help me modify this irule .

I tried but I got error "variable reference required preeciding $"

 

 

 

when HTTP_REQUEST {

if {

                 ([IP::client_addr] contains "10.10.10.1%70") && ([string tolower [HTTP::uri]] contains "/cklauncher/")

                                  }

                                               {

                drop

}                                                             

elseif { [string tolower [HTTP::path]] equals "/" && ( [IP::addr [IP::client_addr] equals 10.10.10.1%70]) } {

# redirect the request

log local0. "issuing redirect request to [HTTP::host][HTTP::uri] from [IP::client_addr]"

HTTP::redirect https://[getfield [HTTP::host] ":" 1]/ckpartner/

}

}
