Figure 5.8 Conﬁguration of primary and secondary Internet connection

Notes:

1. Connection failover is enabled only if at least one probe host is speciﬁed

(WinRoute is not able to detect fails of the primary connection unless at least

one probe host is deﬁned).

2. Probe hosts must be represented by computers or network devices which are

permanently running (servers, routers, etc.). Workstations which are running

only a few hours per day are irrelevant as probe hosts.

3. Probe hosts must not block ICMP Echo Requests (PING) since such requests are

used to test availability of these hosts — otherwise the hosts will be always

considered as unavailable. This is one of the cases where the primary default

gateway cannot be used as the testing computer.
