Network Setup
The following are required:
- Incoming traffic on TCP/IP ports 80, 943 and 4502 be allowed
- Note: Port 80 is a configurable port in Desktop Gateway. You may choose another port if desired
- Make sure the Firewall on the Desktop Gateway PC is not blocking the incoming on these ports
- The Desktop Gateway PC must have these ports forwarded from the internet if you want Desktop Share and Desktop View to be available on the internet
Notes
- Be aware that Desktop View and Desktop Share make outgoing connections on these ports. Under normal circumstances including when behind corporate firewalls and proxies outgoing connections are allowed unless you specifically tell Windows Firewall to block outgoing connections
- Desktop Gateway uses ports 943 and 4502 because of Microsoft Silverlight. The port 943 is used to tell the web browser its "client access policy". This is simply a references to which ports are open for Silverlight and this is specified as 4502 by Desktop Gateway. It is not possible to change these values.
Possible Configurations
There are many ways Desktop Gateway can be configured. Here a few to let you know of your options:
- This would be a typical setup where you have the server and technical support staff in house on your local network.
- This would be a typical setup where you have remote technical support staff as well who may help customers over the internet from their home or remote locations such as from a laptop
- This setup would be typical of an externally hosted solution. Desktop Gateway is a web service and a host that supports web services for .NET 3.5 can host the gateway for you. With this scenario you would need to configure web.config and other configuration files. Nexus Concepts can help you setup for this environment.
