Hi to everyone, I am developing an application in Vb.Net 2005 and have enabled the installation by clickonce, the update occurs before the application starts. My problem is very simple, the server that contains updates is correctly natted to be available from the outside with a public IP. The clients who access from an external network connecting without problems, download software and updates. When local clients are connected to the same network of the server (LAN) can not download anything because they try to access the server with the ip public, and the nat does not work . We can not perform operations on the DNS server or hosts file and not even on the router. I need to figure out if i can use ClickOnce to use more than one distribution server, primary and secondary. I'd like to set as the primary server the public address and the secondary server with internal network ip address. I have read several threads on the MSDN forums, but have not been reflected.
