Using Different ports based on client IP

You just need to create a different pool on port 7777 and then select that pool when the client list matches. You can set up your IP list as a Data Group and then use matchclass to compare the client IP to the list. So something like this: (not syntax tested)

when HTTP_REQUEST {
  if {[matchclass [IP::client_addr] equals $::your_ip_list] }{
    pool 7777_pool
 }
}

Hope that helps,
