This issue may occur if the bandwidth control settings on the firewall are insufficient.

To resolve this issue, configure the physical or virtual firewall with two policies:

Policy 1 -- Allow HTTP and HTTPS from WAN to VDI Network. On this policy there is a guaranteed bandwidth of 50KBps and Traffic priority is medium.
Policy 2 -- Allow AJP, JPS, RDP from the Secure Gateway Server in the VDI Network to the View Server on the LAN

Note: Physical or virtual firewall usage depends upon the physical or virtual type of Security and Connection servers in the environment. For more information about ESX firewall modification, see Securing an ESX Server 3 Configuration in the ESX Server 3 Configuration Guide.

For more information, see Firewall Configuration in the View Manager Administration Guide.
