Troubleshooting the Web Configuration Interface

If you are unable to access the VPN firewall's Web Configuration interface from a PC on your
local network, check the following:
• Check the Ethernet connection between the PC and the VPN firewall as described in the
previous section.
• Make sure your PC's IP address is on the same subnet as the VPN firewall. If you are
using the recommended addressing scheme, your PC's address should be in the range of
192.168.1.2 to 192.168.1.254.
Note: If your PC's IP address is shown as 169.254.x.x:
Windows and MacOS will generate and assign an IP address if the
computer cannot reach a DHCP server. These auto-generated
addresses are in the range of 169.254.x.x. If your IP address is in
this range, check the connection from the PC to the VPN firewall and
reboot your PC.
• If your VPN firewall's IP address has been changed and you do not know the current IP
address, clear the VPN firewall's configuration to factory defaults. This will set the VPN
firewall's IP address to 192.168.1.1. This procedure is explained in
Configuration and Password"
Tip: If you do not want to revert to the factory default settings and lose your
configuration settings, you can 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 you are using the SSL https://address login rather than http://address.
• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure 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.
If the VPN firewall does not save changes you have made in the Web Configuration Interface,
check the following:
• When entering configuration settings, be sure to click the Apply button before moving to
another screen, or your changes are lost.
• Click the Refresh or Reload button in the Web browser. The changes may have occurred,
but the Web browser may be caching the old configuration.
