Link LED is Off If the Link LED is not lit, try the following:
■
Make sure the Firewall is powered on.
■
Make sure the RJ-45 connections are secure. Gently moving the cable
back and forth should not make the Link LED turn on and off.
■
Make sure the wiring follows the CAT-5 specification. See “Pinout
Diagrams” on page 187 for more information.
■
Try replacing the cable with a known good cable.
■
Try using a standard CAT-5 cable. If the problem is on the LAN or DMZ
port, try setting the Uplink/Normal switch to the alternative position.
Ethernet Connection
is Not Functioning
If the Ethernet connection does not work, try the following:
■
Check the physical connections to make sure they are secure.
■
Try replacing the cable with a known good cable.
Cannot Access the
Web interface
If the Firewall does not allow users or the administrator to log in to
establish an authenticated session, try the following:
■
Make sure that the Web browser you are using to access the Web
interface is supported by the Firewall. Netscape Navigator 4 or
Internet Explorer 4 or higher versions are supported.
■
During the initial configuration, make sure that you change the IP
address for the management station to one in the same subnet as the
Firewall, such as
192.168.1.200
.
■
Make sure the Web browser has Java, JavaScript, or ActiveX enabled.
■
Make sure the users are attempting to log into the correct IP address.
The correct address is the management IP Address of the Firewall, and
not the Public Address, if NAT is enabled.
■
Make sure that users are attempting to log in with a valid user name
and password.
