Redirect traffic based on tcp port

You would still define the same pools and then use switch on TCP::local_port to select which pool to send the request to. Here's a simple example:

when CLIENT_ACCEPTED {
    Check the requested port
   switch [TCP::local_port] {
      21  { pool isp1_router_pool }
      25  { pool isp2_router_pool }
      80  { pool isp1_router_pool }
      443 { pool isp1_router_pool }
      default { pool isp1_isp2_router_pool }
   }
}

This might not handle FTP traffic though if the server needs to open a data connection back to the client. This is handled automatically with a VIP and FTP profile though.
