Using the Network Diagnostic Tools 65

Find Network Path

Use the Find Network Path tool to show on which port, LAN, WAN or

DMZ where appropriate, an IP host is located. This is helpful to determine

if the Firewall is properly configured. For example, if the Firewall thinks

that a machine known to be on the Internet is located on the LAN port,

then there is a problem with the configuration of the network or intranet

settings. Find Network Path also shows if the target node is behind a

router, and the Ethernet address of the target node or router. Find

Network Path also shows which router a node is using, which can help

isolate router configuration problems.

1 Select Find Network Path from the Choose a diagnostic tool menu.

2 Type the IP address of the device and click Go. The test takes a few

seconds to complete.

If the network path is incorrect, check the intranet, static route, and DMZ

settings.

Find Network Path requires an IP address. Use the Firewall’s DNS Name

Lookup tool to find the IP address of a host.

Ping

The Ping tool bounces a packet off a machine on the Internet back to the

sender. This test shows if the Firewall is able to contact the remote host. If

users on the LAN are having problems accessing services on the Internet,

try pinging the DNS server, or other machine at the ISP’s location. If this

test is successful, try pinging devices outside the ISP. This shows if the

problem lies with the ISP’s connection.

1 Select Ping from the Choose a diagnostic tool menu.

2 Type the IP address of the device being pinged and click Go.Thetest

takes a few seconds to complete.

Ping requires an IP address. Use the Firewall’s DNSNameLookuptool to

find the IP address of a host.

Packet Trace

Use the Packet Trace tool to track the status of a data packet or

communications stream as it moves from source to destination. This is a

useful tool to determine if a packet or communications stream is being

stopped at the Firewall, or is lost on the Internet.

Select Packet Trace from the Choose a diagnostic tool drop-down list.
