5.2 Connection Failover
59
Primary connection
Parameters of the primary Internet connection. The connection can be defined as
follows:
• network interface with a default gateway
• dial-up connection
Only interfaces and dial-up connections defined through the Interfaces tab are avail-
able in the Interface entry (see chapter 5.1).
Default settings (default gateway and a corresponding interface) are detected in
the operating system after WinRoute installation, or when the Enable automatic
connection failover option is enabled the first time. This can be also be achieved by
clicking on the Detect button.
If no default gateway is defined in the operating system (i.e. when the primary con-
nection is performed by a dial-up which is currently hung-up), a primary connection
cannot be detected automatically — the primary connection must be set by hand.
Secondary connection
Use this section to set parameters for a secondary Internet connection which will be
established in case that a primary connection dropout is detected. The secondary
connection can be defined as a network interface with a default gateway or as a dial-
up connection (like for the primary connection).
Note: The same adapter as for the primary connection can be used, however, the
default gateway must be different. This way we can be sure that a different router
in the same network (subnet) will be used when the primary connection is dropped
out.
Dial-up Use
The following issues must be taken into consideration if a dial-up is used for the primary
and/or the secondary connection:
1. Connection failover is relevant only if performed by a permanent connection (using
a network adapter or a permanently connected dial-up). If an on-demand dial-up
(or a dial-up connection dialed by hand) was used for the primary connection, the
secondary connection would be established automatically after each hang-up of the
primary connection.
2. In case of manually dialed secondary line a problem might occur if the Hangup if
idle option is enabled. If the secondary line is hung-up automatically, WinRoute does
not dial it automatically (until the connections are refreshed and the next failure of
the primary connection).
