Pinging to Test LAN Connectivity
Most TCP/IP terminal devices and firewalls contain a ping utility that sends an
ICMP echo-request packet to the designated device. The device 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 from your PC to your security appliance
STEP 1 On your PC, click the Windows Start button, and then click Run.
STEP 2 Type ping <IP_address> where <IP_address> is the IP address of the security
appliance. Example: ping 192.168.75.1.
STEP 3 Click OK.
STEP 4 Observe the display:
If the path is working, you see this message sequence:
Pinging <IP address> with 32 bytes of data
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message sequence:
Pinging <IP address> with 32 bytes of data
Request timed out
STEP 5 If the path is not working, test the physical connections between the PC and the
security appliance:
If the LAN port LED is off, go to the “LED displays” section on page B-1 and
follow instructions for “LAN or Internet port LEDs are not lit.
Verify that the corresponding link LEDs are lit for your network interface card
and for any hub ports that are connected to your workstation and firewall.
STEP 6 If the path is still not up, test the network configuration:
Verify that the Ethernet card driver software and TCP/IP software are
installed and configured on the PC.
Verify that the IP address for the security appliance and PC are correct and
on the same subnet.
