XenApp iApp ICA Proxy not working (I think)

Thanks Michael,

I've configured the iApp so that it's successfully proxying storefront to a different VLAN, applying a certificate, and authenticating logons. However, the ICA client is attempting to contact the ICA server directly, not via the F5 storefront Virtual Server. Can you explain what I need to change so that the clients can all use that same Virtual Server IP?
