Network Setup menu options
Internet connection failover
Select a Test Type. The Ping test is usually appropriate. Available options are:
5
• Default – Allows you to determine if the connection is up.
• Ping – Sends network traffic to a remote host at regular intervals, if a reply is received, the connection
is deemed to be up.
• Custom [advanced users only] – Allows you to enter a custom console command to run to determine
whether the connection is up. This is typically a script you have written and uploaded to the UTM
Firewall appliance.
You can adjust the time-outs for the failover test; however, the defaults are usually suitable.
In the Test Delay field, enter the number of seconds to wait after starting this connection before testing
6
whether it is functioning correctly. Use a longer delay for connection types that are slow to establish, such
as dialout. The defaults vary depending on the type of connection, and are as follows:
• 5 (direct connection)
• 10 (PPTP/PPPoE connection)
In the Retry Delay field, enter the number of seconds to wait after a connection test fails before
7
attempting the test again. The defaults vary depending on the type of connection, and are as follows:
• 5 (direct connection)
• 30 (PPTP/PPPoE connection)
In the Connection Attempts field, enter the number of times to try a connection. Once the UTM Firewall
8
appliance has ceased testing this connection, manual intervention is required to re-establish the
connection.
• Default: 2147483647
Click Next to configure settings specific to the Test Type.

• If you selected a Test Type of Default, no further configuration is required. Click Finish. The next step
is to modify the failover levels. See
