Prevent Internet Access did not work for Dial In Connections RRS feed

  • Question

  • Hello,

    we have installed SteadyState at some laptops and using the Prevent InternetAccess Funktion. For a connection over a LAN cable or Wireless LAN it works fine. The user can only open the enabled websites.

    But if he connects to the internet over a DialIn Connection maybe over a UMTS Modem the prevent internet access funktion did not work. He can open every website in the IE.


    Windows Vista
    IE 7 or 8
    Windows Steady State 2.5

  • Firstly, I would like to inform you that when you select the “Prevent Internet access (except Web Sites below)” option, the system will set the proxy server in IE to a non-exist one (NoInternetAccess) and add websites allowed to the “Exceptions”. The "Use the same proxy server for all protocols" option is checked. Thus, all website accesses except for those allowed sites are blocked. According to its working theory, if you already have a proxy server and which is the exclusive Internet access, “Prevent Internet access” option will not work.


    Let's manually set proxy server on DialIn connection and check the result this time.


    1. To avoid confusion, please clear the “Prevent Internet access (except Web sites below)” option in SteadyState first.

    2. Click Start and click Run.

    3. Type “inetcpl.cpl” in the open box, and then press Enter.

    4. Select the Connections tab, click LAN Settings.

    5. Uncheck “Automatically detect settings”, select “Use a proxy server for your LAN. Input NoInternetAccess to the Address box, 80 to the port box.

    6. Click Advanced, select “Use the same proxy server for all protocols”

    7. Type some websites in the Exceptions space. Click OK.

    8. Check if websites can be accessed or not.
