Warning

WinRoute is running in the operating system as a service. Therefore, external applica-

tions and operating system’s commands will run in the background only (in the SYSTEM

account). The same rules are applied for all external commands and external programs

called by scripts. Therefore, it is not highly unrecommended to use interactive applica-

tions (i.e. applications with user interaction) for the actions described above. Otherwise.

interactive applications are running as “invisible” until the next reboot or until the partic-

ular process is ended by the Windows Task Manager. Under specific circumstances, such

application might also block other dials or hang-ups.

6.3 Connection Failover

WinRoute allows guarantee Internet connection by an alternative (back-up) connection (so

called connection failover). This connection failover is launched automatically whenever fail-

ure of the primary connection is detected. When WinRoute finds out that the primary con-

nection is recovered again, the secondary connection is disabled and the primary one is re-

established automatically.

Requirements

The computer hosting WinRoute must have two network interfaces for Internet connection:

a leased line (Ethernet, WiFi) or a dial-up with persistent connection (CDMA, PPPoE) for primary

connection and a leased line or a dial-up for secondary (failover) connection.

This connection type also requires one or more network cards for connection of individual

segments of the LAN. Default gateway must NOT be set on any of these cards (cards for the

LAN)!

In case of dial-ups, it is also necessary to define corresponding telephone connection in the

operating system. It is not necessary that login data for telephone connections are saved in

the system, this information can be specified directly in WinRoute.

Both the primary and the secondary link may be configured automatically by the DHCP proto-

col. In that case, WinRoute looks all required parameters up in the operating system.

It is recommended to check functionality of both the primary and the secondary link out

before installing WinRoute:

If these links are two dial-ups, dial one after the other and check the Internet connec-

tion.

If the primary link is leased and the secondary a dial-up, test the primary link con-

nection first and the secondary connection second. Dialing of the link opens (creates)
