ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
Troubleshoot a TCP/IP Network Using the 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. You can easily
troubleshoot a TCP/IP network by using the ping utility in your PC or workstation.
Test the LAN Path to Your VPN Firewall
You can ping the VPN firewall from your PC to verify that the LAN path to the VPN firewall is
set up correctly.
To ping the VPN firewall from a PC running Windows 95 or later:
1. From the Windows toolbar, click Start and select Run.
2. In the field provided, type ping followed by the IP address of the VPN firewall; for example:
ping 192.168.1.1
3. Click OK. A message, similar to the following, should display:
Pinging <IP address> with 32 bytes of data
If the path is working, you will see this message:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the path is not working, you will 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 that the LAN port LED is on. If the LED is off, follow the instructions in
LAN or WAN Port LEDs Not On on page 295.
- 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 VPN
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 VPN firewall and your workstation are correct
and that the addresses are on the same subnet.
