Guessing you have only the one port set on the forwarding VS that the clients are configured to go to and you are using explicit proxy?

Markie Parkie, This was/is a wildcard VS so it listens for all IPs/Ports. We had this same setting on our 3900s with no issues; however when we went to vCMP Guests on i5800s we started seeing these issues. Above describes the article we used to resolve this. The only caveat is to watch for this issue to crop up after upgrades.
