>Ok. There is a little bit progress after bypassing the proxy for local address. If I invoke http://wsn_server/mywebapp, it works in the server but when trying to do it in the workstation it doesn't but gives "browser error." http://localhost/mywebapp or http://127.0.0.1/mywepapp in the workstation, gives "the page cannot be displayed." Is there anything I am missing???

Are you running IIS and the application on both the workstation and the server? I am guessing that you are just running it on the server, if so then what is the IP addess of the SERVER? What happends if you do http://SERVERIP/mywebapp on the Workstation, where SERVERIP is the server's IP address in the form -192.20.55.234? Because if you enter http://127.0.0.1/mywebapp on the workstation it will look for a web server and the application running on the workstation not on the server. Hope this helps and I'm not totally off in left field, or stating the obvious.
