Redirect Source IP to Pool

It would probably be easiest to set up a second pool with the four members and then use the IP::addr command (Click here) an iRule to check the client IP address (retrieved using IP::client_addr Click here) and select the second pool. Or if possible, it would probably be easier to create a new virtual server which references the second pool and have that single client access the second virtual server.

Here is an example of the first option:

 
 when CLIENT_ACCEPTED { 
  
     Check if client IP is 1.1.1.1 
    if {[IP::addr [IP::client_addr] equals 1.1.1.1]}{ 
  
        Select the second pool 
       pool second_pool 
    } 
     Any other client will use the default pool on the VIP 
 }
