applications such as AutoUpdate and Anti-Virus. If Enable WAN Failover is selected on the
Modem > Failover page, the pings generated by the probe can trigger the modem to dial
when no WAN Ethernet connection is detected. If the Primary Profile cannot connect, the
modem uses the Alternate Profile 1 to dial an ISP.
Manual Connection - Selecting Manual Connection for a Primary Profile means that a
modem connection does not automatically occur. You must click the Connect button on the
Network > Settings page for the dialup connection to be established. Also, WAN Failover
does not automatically occur.
Caution If you are configuring two dial-up profiles for WAN failover, the modem behavior should be
the same for each profile. For example, if your Primary Profile uses Persistent Connection,
your Secondary Profile should also use Persistent Connection.
Caution If you enable Persistent Connection for the modem, the modem connection remains active
until the WAN Ethernet connection is reactivated or you force disconnection by clicking
Disconnect on the Configure page.
13. If you selected either Connect on Data or Manual Connection, enter the number of
minutes a dial-up connection is allowed to be inactive in the Enable Inactivity Disconnect
(minutes) field.
14. Select the connection speed from the Max Connection Speed (bps) menu. Auto is the
default setting as the SonicWALL security appliance automatically detects the connection
speed when it connects to the ISP or you can select a specific speed option from the menu.
15. Select Enable Max Connection Time (minutes) if the connection is terminated after the
specified time. Enter the number of minutes for the connection to be active. The value can
range from 0 to 1440 minutes. This feature does not conflict with the Inactivity Disconnect
setting. If both features are configured, the connection is terminated based on the shortest
configured time.
16. If you select Enable Max Connection Time (minutes), enter the number of minutes to
delay before redialling the ISP in the Delay Before Reconnect (minutes). The value can
range from 0 to 1440, and the default value is 0 which means there is no delay before
reconnecting to the ISP.
17. If you have call waiting on your telephone line, you should disable it or another call can
interrupt your connection to your ISP. Select Disable Call Waiting and then select
command from the list. If you do not see your command listed, select Other, and enter the
command in the field. If you are not sure which command to use, see the documentation
that came with your phone service or contact your phone service provider.
18. If the phone number for your ISP is busy, you can configure the number of times that the
SonicWALL security appliance modem attempts to connect in the Dial Retries per Phone
Number field. The default value is 0.
19. Enter the number of seconds between attempts to redial in the Delay Between Retries
(seconds) field. The default value is 5 seconds.
20. Select Disable VPN when Dialled if VPN Security Associations (SAs) are disabled when
the modem connects to the ISP. Terminating the dial-up connection re-enables the VPN
SAs. This is useful if you want to deploy your own point-to-point RAS network and want
packets to be sent in the clear to your intranets.
