Deploying F5 with VMware view and Horizon view

Downloaded the iApp and configured F5. All configured components are green. Hit the VIP that load balances the UAG servers. You get a VMware Horizon page with two options, install the Horizon client and that access works. If you pick VMware Horizon HTML access, it takes 5 or 6 mins to get the login. Go directly to UAG servers and the HTML access works. So there is something wrong when going thru F5. The VIP and real server is on the same network.
