Virtual Server for RPC portmapper based application

We have a application which is using RPC Portmapper. Can someone help me configuring Virtual Server which can support the RPC application?

Here is the dump when we directly access the server

If I connect via Virtual Server it fails and doesnt even negotiate on ports.
