I have used the solution provided by this thread: Can I access ASP.NET Development server in an intranet?I have tried both JavaTCPtunnel and Pocketsoap TCP trace, but they both return Bad Request - Inavlid hostname. I can see that a connection is made, but still this error is returned.Router and firewall are both forwarded. Do I need to setup something in the IIS dev server? Why does this work for everyone but not for me?
