ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336Gv2 Reference Manual
If your VPN 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. You may configure your PC manually with DNS
addresses, as explained in your operating system documentation.
•
Your PC may not have the VPN firewall configured as its TCP/IP gateway.
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 VPN Firewall
You can ping the VPN firewall from your PC to verify that the LAN path to your network
storage is set up correctly.
To ping the network storage from a PC running Windows 95 or later:
1.
From the Windows toolbar, click Start and choose 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 the LAN port LED is on. If the LED is off, follow the instructions in
or WAN Port LEDs Not On"
