168Troubleshooting the NVG

User Unable to Connect to the VPN Gateway through the Net Direct Client

Start by verifying on your own PC that Net Direct works towards the same VPN Gateway as the end-user’s device.

Then check the following in the specified order:

Step Action

1Is the user logged in to the Portal? Check in the CLI.

You can choose to limit the output of logged in users to a particular VPN by providing the VPN number as a modifier to the users command. To limit the output further, you can also provide one or more initial letters of a user name, directly followed by an asterisk (*).

>> Information# users 1 s*

If the user is not logged in, make sure the user can log into the Portal at all. See “A User Fails to Connect to the VPN” (page 163).

2Is Net Direct enabled and configured correctly?

See the "Net Direct" chapter in the Application Guide for VPN for instructions on how to enable Net Direct and how to configure an IP pool.

3Is the Net Direct link visible to the end-user on the Portal’s Home tab?

If not, the user may belong to a group that does not have access to the linkset where the Net Direct link is included. See the "Net Direct" chapter in the Application Guide for VPN for instructions on how to configure a Net Direct link and map the linkset to the desired group.

4For Windows, is the Net Direct ActiveX control present on the end-user’s PC?

Let the end-user check the following: In Internet Explorer, on the Tools menu, select Internet options. On the General tab, Under Temporary Internet Files, click Settings. Click View objects. Verify that the Net Direct control is installed and that the version corresponds to the VPN Gateway ’s version.

If the ActiveX control cannot be started, Net Direct tries to start the Java applet instead.
