Virtual server with port translation

We have a VS where we are doing ssl offload and forwading data to pool of servers on specific ports.

client ---443---> VS ------- Node1 and Node2 on both port 9090 and 9091

I created a pool for with Node1 9090, Node1 9091 m Node 2 9090 and NOde2 9091. This is working . But want to know if there is a more better way to do this .
