iRule to modify the client IP to Virtual Server IP

I am trying to load-balance print server connections between 2 windows print servers.

 

 

When we try to connect to the VS address, we get a network path not found error. However, I can use the ip address of eiher of the print servers (not the VS),I can view all the queues and print to them.

 

 

It is working with Cisco CSS. But I did client NAT on the CSS which changes the client's IP to VS. I also remembered that we added a loopback interface on the server for CSS to work.

 

 

I am trying the same way on the BigIP but it is not successful.
