== Problems with establishing a VPN connection using the VPN client  ==
 
 
 
=== '''Verify That You Have An Internet Connection'''  ===
 
 
 
Try accessing a site that doesn't require VPN to ensure that your Internet connection is indeed active.
 
 
 
=== '''Try Disabling Local Firewalls'''  ===
 
 
 
You might have a firewall program running on your computer that should be disabled such as, Windows Firewall (included with Windows XP Service Pack 2), Zone Alarm, etc.&nbsp;When you are trying to connect, if you are prompted that the VPN Client is trying to access the Internet, be sure to "Allow" or "Unblock".<br>
 
 
 
=== '''Opt-out of Domain Helper Services'''  ===
 
 
 
Many ISPs have domain helper services that redirect traffic, for a variety of purposes. Occasionaly, this can cause problems with VPN. Contact your ISP to determine if and how you can opt-out of Domain Helper Services. For example, Comcast has an opt-out page here: https://dns-opt-out.comcast.net<br>
