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 

.

–

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.

After verifying that the LAN path works correctly, test the path from your PC to a remote device. 
From the Windows run menu, type:

 <IP address>

where <IP address> is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not 
receive replies:

–

Check that your PC has the IP address of your VPN firewall listed as the default gateway. 
If the IP configuration of your PC is assigned by DHCP, this information will not be 
visible in your PC’s Network Control Panel. 

–

Check to see that the network address of your PC (the portion of the IP address specified 
by the netmask) is different from the network address of the remote device.

–

Check that your cable or DSL modem is connected and functioning.

–

If your ISP assigned a host name to your PC, enter that host name as the Account Name in 
the Basic Settings menu.
