Reference Manual for the ProSafe VPN Firewall FVS114

Troubleshooting 9-5

202-10098-01, April 2005

Configure your firewall to spoof your PC’s MAC address. This can be done in the Basic

Settings menu. Refer to “How to Manually Configure Your Internet Connection” on

page 3-11.

If your firewall can obtain an IP address, but your PC is unable to load any Web pages from the

Internet:

• Your PC may not recognize any DNS server addresses.

A DNS server is a host on the Internet that translates Internet names (such as www addresses)

to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS

servers for your use. Alternatively, you may configure your PC manually with DNS addresses,

as explained in your operating system documentation.

• Your PC may not have the firewall configured as its TCP/IP gateway.

If your PC obtains its information from the firewall by DHCP, reboot the PC and verify the

gateway address.

Troubleshooting a TCP/IP Network Using a Ping Utility

Most TCP/IP terminal devices and firewalls contain a ping utility that sends an echo request packet

to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP

network is made very easy by using the ping utility in your PC or workstation.

Testing the LAN Path to Your Firewall

You can ping the firewall from your PC to verify that the LAN path to your firewall is set up

correctly.

To ping the firewall from a PC running Windows 95 or later:

1. From the Windows toolbar, click the Start button and select Run.

2. In the field provided, type ping followed by the IP address of the firewall, as in this example:

ping 192.168.0.1

3. Click on OK.

You should see a message like this one:

Pinging <IP address> with 32 bytes of data

1 2 ... 140 141 142 143 144 145 146 147 148 149 150 ... 211 212
