Chapter 4 Troubleshooting 93

For ActiveX Scripts, Java, and JavaScript*, you must enable both ActiveX and Java programs in Internet Explorer, and enable both Java and JavaScript in Netscape Communicator for proper VPN Router Web management windows. These options are enabled by default on both Web browsers.

Enabling Web browser options

To make sure these options are enabled in Internet Explorer, from the Internet Explorer menu bar, select View > Options > Security, and select:

Run ActiveX scripts—If this option is disabled, navigational titles are not updated, and the Logoff and Help buttons do not work.

Enable Java programs—If this option is disabled, navigational menus do not appear.

To make sure these options are enabled in Netscape*, from the Netscape menu, select Edit > Preferences > Advanced, and select:

Enable Java – If this option is disabled, navigational menus do not appear.

Enable JavaScript – If this option is disabled, navigational titles are not updated, and the Logoff and Help buttons do not work.

Long delays when Web browsing

Cause: HTTP—Sometimes when you HTTP the Web interface, you can experience long delays (greater than five minutes).

Action: Wait until the requested window is fully delivered before clicking on a new window request.

Improving performance with Internet Explorer 4.0

Nortel recommends that you create a DNS server entry for your management IP address. This alleviates a noticeable delay in loading the initial Main menu and navigational windows.
