So as you’re developing / debugging a Visual Studio 2010 web app, you may want to access the local web server from a remote machine. Visual Studio will be accessible locally using an address like: http://localhost:5524, but if you try from another machine on your network using the ip address ie: http://192.168.4.2:5524, you won’t be able to reach the solution.

The easiest way to get this working:
1. Download SPI Port Forward.
2. Install SPI Port Forward.
3. The config is a little backwards in my opinion, so after running SPI Port Forward, enter the remote port you want to use in the  “Local Port” text box (ie: 8080), and in the “Remote Host” enter “localhost” (usually) and in the “Remote Port” enter your local Visual Studio debugging port (in my example, 5524.
4. Click Activate

You should now be able to access your Visual Studio web app (provided it’s open and running) using http://(your machine ip)/(the port you choose above) ie: http://192.168.4.2:8080

Happy Testing!
