cannot reach a DHCP server. These autogenerated addresses are in the range of 
169.254.x.x. 

If your IP address is in this range, check the connection from the computer to the VPN 
firewall and reboot your computer.

If your VPN firewall’s IP address has changed and you do not know the current IP 
address, use an IP address scanner application on your network to discover the IP 
address. These applications are available on the Internet free of charge.

You can also reboot the VPN firewall and use a sniffer to capture 
packets sent during the reboot. Look at the ARP packets to locate the 
VPN firewall’s LAN interface address.

Make sure that you are using the SSL https://address login rather than the http://address 
login.

Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using 
Internet Explorer, click the Refresh button to be sure that the Java applet is loaded.

Try quitting the browser and launching it again.

Clear the browser’s cache.

Make sure that you are using the correct login information. The factory default login name 
is admin, and the password is password. Make sure that Caps Lock is off when entering 
this information.

For you to be able to configure the VPN firewall, your computer’s IP 
address does not need to be on the same subnet as the VPN firewall.

If the VPN firewall does not save changes that you made in the web management interface, 
do the following:

When entering configuration settings, be sure to click the Apply button before moving to 
another menu or tab, or your changes are lost. 

Click the Refresh or Reload button in the web browser. The changes might have 
occurred but the web browser might be caching the old configuration.

A number of things could be causing a time-out error. Try the following troubleshooting steps:

Check whether other computers on the LAN work correctly. If they do, ensure that your 
computer’s TCP/IP settings are correct. If you use a fixed (static) IP address, check the 
subnet mask, default gateway, DNS, and IP addresses (see 

36).
