Here are a few items to check if you are having trouble connecting to your VPN:
Make sure that Connect Tunnel is running and actively connected to the network. For more information,
see Viewing Connect Tunnel Status.
Verify in the Connect Tunnel Properties dialog box that you are initiating a connection to the correct
host name or IP address. For more information, see Connecting to a Different VPN.
Verify in the Connect Tunnel Properties dialog box that you are initiating a connection to the correct
login group. For more information, see Choosing a Login Group.
If you use a personal firewall, you may need to reconfigure the firewall before you can access the VPN.
To do this, configure the firewall to allow SnwlConnect.exe traffic to access the Internet, and add the
VPN’s host name or IP address as a trusted host or zone.
Authentication may require that you have a particular client certificate on your device. If you make
changes to the certificates installed on your computer between logon attempts, update the list
presented during login by clicking Refresh.
