Nortel VPN Router Troubleshooting
• 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.
