Procedure 8-5:   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 on 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
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
Wrong physical connections
— Make sure the LAN port LED is on. If the LED is off, follow the instructions in 
.
— Check that the corresponding Link LEDs are on for your network interface card and 
for the hub ports (if any) that are connected to your workstation and firewall.
Wrong network configuration
— Verify that the Ethernet card driver software and TCP/IP software are both installed 
and configured on your PC or workstation.
— Verify that the IP address for your firewall and your workstation are correct and that 
the addresses are on the same subnet.
