Troubleshooting

If the target computer cannot be located, you will receive the message [Request timed out]. Using the ping command, you can test whether the path to the ADSL Barricade is working (using the preconfigured default LAN IP address 192.168.1.1) or another address you assigned.

You can also test whether access to the Internet is working by typing an external address, such as that for www.yahoo.com (216.115.108.243). If you do not know the IP address of a particular Internet location, you can use the nslookup command, as explained in the following section.

From most other IP-enabled operating systems, you can execute the same command at a [Command Prompt] or through a system administration utility.

oNslookup

You can use the nslookup command to determine the IP address associated with an internet site name. You specify the common name, and the nslookup command looks up the name in on your DNS server (usually located with your ISP). If that name is not an entry in your ISP's DNS table, the request is then referred to another higher-level server, and so on, until the entry is found. The server then returns the associated IP address.

On Windows-based computers, you can execute the nslookup command from the Start menu. Click the [Start] button, and then click [Run]. In the Open text box, type the following: nslookup.

Click [OK]. A [Command Prompt-nslookup] window displays with a bracket prompt (>). At the prompt, type the name of the internet address your are interested in, such as www.microsoft.com.
