You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.
Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.You can access using IP address. Make sure
Turn off your firewall
If you do have a firewall turn it off while you try connecting for the first time, you can sort that out later.
