Broadband network communications such as cable and DSL provide the bandwidth necessary for effective network remote access over the Internet. Remote access over public networks should be protected from eavesdropping by employing the encryption technology used in VPN (Virtual Private Network) connections that effectively scrambles information so that it is unreadable. Configure Windows computers to accept and initiate VPN connections over a broadband connection using VPN services included with the Windows operating system.
Select the "Start" or "Globe" button located in the lower left corner of the Windows 7 Professional or Ultimate PC desktop, then click "Control Panel." Double-click the "Network and Sharing Center" icon in the "Control Panel" window that appears and click "Change Adapter Settings" in the "Network and Sharing Center" window.
Select the "File" menu and click "New Incoming Connection" in the menu that appears. In the window that appears, select each account that should have remote access permission to the Windows 7 Professional or Ultimate computer. Then click "Through the Internet" and select the "Next" button.
Select "Internet Protocol Version 4 (TCP/IPv4)" from the list presented and select the "Properties" window. Select the "Allow callers to access my local area network" check box in the "Incoming IP Properties" window. Select the "Assign IP addresses automatically using DHCP" radio button and select the "OK" button.
Select the "Allow Access" button to save the settings and select the "Close" button to complete the VPN server connection configuration.
Select the "Start" or "Globe" button on the Windows 7 remote client computer and select "Control Panel," then select "Network and Internet." Select "Network and Sharing Center" in the "Network and Internet" window that appears and then select "Set up a new connection or Network."
Select "Connect to a workplace," then select the "Next" button. Select "Use my Internet connection (VPN)" in the window that appears. Enter the Internet side IP of the Windows 7 Professional or Ultimate computer that is configured to provide VPN remote access and enter a name for the VPN remote access connection in the "Destination name" field, then select the "Next" button.
Enter the credentials of an account that has permission to connect to the Windows 7 Professional or Ultimate VPN computer into the "User name" field and "Password" field and then select the "Create" button. Select "Connect Now" to remotely access the private network through the newly configured VPN connection.
If the Windows 7 Professional or Ultimate computer network is protected by a firewall, then set up "port forwarding" on the firewall to forward port 1723 connections to the IP address of the Windows 7 Professional or Ultimate computer and enable "PPTP" pass through. Then use the Internet IP address of the firewall to connect to the Windows 7 Professional or Ultimate computer rather than the IP address of the computer.
