Configuring Dial Backup

To change your Business Secure Router's Dial Backup settings, click WAN, then
the Dial Backup tab. The screen appears as shown in
NN47922-500
Description
Configuration of this field is optional. If you do not enter an IP address
here, the Business Secure Router uses the default gateway IP
address. Configure this field to test your Business Secure Router's
WAN accessibility. Type the IP address of a reliable nearby computer
(for example, your ISP's DNS server address). If you are using PPTP or
PPPoE Encapsulation, type 0.0.0.0 to configure the Business Secure
Router to check the PVC (Permanent Virtual Circuit) or PPTP tunnel.
Enter the number of times Business Secure Router will attempt to
connect to the Internet before traffic is forwarded to the backup
gateway.
Type the number of seconds for the Business Secure Router to wait
between checks to see if it can connect to the WAN IP address (Check
WAN IP Address field) or default gateway. Allow more time if your
destination IP address handles lots of traffic.
Type the number of seconds for your Business Secure Router to wait
for a ping response from the IP Address in the Check WAN IP
Address field before it times out. The WAN connection is considered
down after the Business Secure Router times out the number of times
specified in the Fail Tolerance field. Use a higher value in this field if
your network is busy or congested.
Click Apply to save your changes to the Business Secure Router.
Click Reset to begin configuring this screen afresh.
