View Client with Local Mode data is downloaded and uploaded through TCP port 902 by default. In addition, View Transfer Server publishes View Composer images through TCP port 902. If you intend to use View Client with Local Mode, TCP port 902 must be accessible to your ESX/ESXi host, and UDP port 445 must be accessible to the network share if you use a network share for the View Transfer Server repository.

If necessary, to comply with organization policies or to avoid contention, you can change which port numbers are used.
