Norton 360 is a comprehensive computer security solution software package produced by Symantec. Besides providing antivirus and anti-spyware protection, Norton 360 also provides an embedded computer firewall to help further protect your computer against computer hackers. A common problem that arises, however, is that Norton 360's firewall can inadvertently block virtual private network (VPN) connectivity if you do not configure the firewall to permit the VPN.
Open Norton 360 by double-clicking the program icon on your computer's desktop or by selecting the Norton icon from the Windows task tray.
Update Norton 360 by selecting the "Run Live Update" menu option. Older versions of Norton 360 would inadvertently block all VPN traffic, independent of firewall rules.
Select the "Task and Settings" menu button and choose the "Advanced Settings" option.
Choose the "Firewall Protection Settings" option, select the "Add" menu button and choose the "VPN" application from the file chooser.
Select the "Permit" menu button and choose incoming and outgoing traffic followed by the "Next" button.
Choose the "Any Computer" menu button followed by the "Next" option.
Select the option to apply to "All Ports" and "All Types of Communication" followed by the "Next" menu button.
Enter a text description for the firewall rule and click the "Next," "Finish" and "Close" menu buttons to complete configuring Norton 360 for a VPN connection.
