User manual

Select a Test Type. The Ping test is usually appropriate.
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 SnapGear unit.
Always Up means no test is performed, and Internet failover is disabled for this
connection.
If you wish, you may fine tune the timeouts for the failover test, however the defaults are
usually suitable.
Test Delay is the number of seconds to wait after starting this connection before
testing whether it is functioning correctly, a longer delay is used for connection types
that are slow to establish, such as dialout.
Retry Delay is the number of seconds to wait after a connection test fails before re-
attempting the test.
Times to attempt this connection is the number of times to try a connection before
giving up. Once the SnapGear unit has given up trying this connection, manual
intervention is required to re-establish it.
Click Next to configure settings specific to the Test Type.
If you selected a Test Type of Always Up, no further configuration is required. Skip
ahead to Modify failover levels (primary, secondary, tertiary).
