Tip & How-To about Computers & Internet

Why can Networked Devices not be used when a VPN connection is active?

With most VPNs, as soon as the VPN connection is established, it will take precedence over all other network connections. Access to the Internet (other than to keep the VPN connection itself alive) will go via the VPN and the corporate network you are connected to, rather than the local ISP. Furthermore, access to the local network is temporarily disabled.

As a result, your local print server may not be accessible,
you cannot use devices via the Network USB hub, or the USB ports on your router (if it has these), you may not even be able to access your local router's configuration page or ping the router or other machines in the local network.

This is done because of security reasons.
When a computer is connected to a corporate network via a VPN, the administrator needs to make sure that that machine can not act as a some form of a gateway enabling other machines in the local network to access that corporate network in any way. For that reason, the machine connecting via the VPN must temporarily be isolated from the local network.

what is vpn server


Point-To-Point Tunneling Protocol (PPTP) is another tunneling protocol used to connect a remote client to a private server over the Internet. PPTP is one of the most widely used VPN protocols because of it's straightforward configuration and maintenance and also because it is included with the Windows operating system.
http://electronicshelponline.blogspot.com/ A VPN or Virtual Private Network is a method used to add security and privacy to private and public networks, like WiFi Hotspots and the Internet. VPNs are most often used by corporations to protect sensitive data.

hello i have a problem with Archos 5 Internet tablet... our isp give me a ip adress And Vpn connection & i can connect with laptop but in archos i connect to wireless access point but i can't connect VPN because archos os (android) dont have vpn advanced security setting and at last i cannot connect to the internet.... please solve my problem


Hi, Unfortunatly there is no solution with your current set up, you will need a medium grade router like a draytek 2820, that can establish the vpn from itself rather than from the computer, this way the vpn is established from the router, and when your archos connects to the router it will also have access to the vpn.

VPN misconfigured after belkin router was configured XP


Hi Grahmmy..
I am myself a (cisco certified network associate)CCNA, we have configured several VPNs on XP, please try these steps and im sure you'll be able to reconfigure the Virtual private network on your XP...
  1. First open the control panel by clicking start,open the Network Connections item in Control Panel. A list of existing dial-up and LAN connections will appear.
  2. Choose the 'Create a new connection' item from the left-hand side of the window. The Windows XP New Connection Wizard will appear on the screen.
  3. First click Next to begin the wizard, then choose the 'Connect to the network at my workplace' item from the list and click Next.
  4. On the Network Connection page of the wizard, choose the 'Virtual Private Network connection' option and click Next.
  5. Enter a name for the new VPN connection in the 'Company Name' field and click Next. The name chosen need not match the name of an actual business.
  6. Choose an option on the 'Public Network' screen and click Next. The default option, 'Automatically dial this initial connection' can be used if the VPN connection will always be initiated when the computer is not already connected to the Internet. Otherwise, choose the 'Do not dial the initial connection' option. This option requires that the public Internet connection be established first, before this new VPN connection will be initiated.
  7. Enter the name or IP address of the VPN remote access server to connect to, and click Next. Company network administrators will provide this information.
  8. Choose an option on the "Connection Availability" screen and click Next. The default option, 'My Use Only,' ensures that Windows will make this new connection available only to the currently logged on user. Otherwise, choose the 'Anyone's use' option.
  9. Click Finish to complete the wizard. The new VPN connection information has been saved. Good luck ;-)
