Ping test
Use this procedure to perform a ping test within the Management Console. Use the ping test to verify
packets are able to reach and return from a specific host either on the Internet or on your local network.
1
From the System menu, click Diagnostics > Network Tests tab. The Network Tests page appears.
2
Enter the IP Address of the box you want to ping in the IP Address of Remote Machine field.
3
[Optional] Select an interface from the Source Interface list.
• Default: None.
Tip: If you are trying to ping the remote end of an IPSec tunnel, use the LAN interface of the appliance
where the LAN network is defined as the local network. Otherwise, the ping will fail.
4
[Optional] To perform a reverse DNS names lookup on IP addresses, select the Lookup DNS Names
checkbox.
5
Click Ping. The results of the test are displayed ( Figure 374 ).

Traceroute test
Use this procedure to perform a traceroute test within the Management Console. The Traceroute test traces
the network path that packets travel as they attempt to reach and return from a specific host either on the
Internet or on your local network.
Note: Since the UTM Firewall appliance runs on the Linux OS, it uses UDP probes in traceroute by default. This is
in contrast to the Windows platform, which uses ICMP. Depending on what is blocked upstream, you may observe
different results between platforms.
