Example: Creating ISP Connection Settings (NSM Procedure)
You configure the security device to dial to an ISP account if a failover to the serial interface occurs and there is traffic to be sent. You can configure up to four ISP connections, assigning each a different priority number (1 is the highest priority). The priority number determines the order that the device uses in attempting the dial-up connection; the ISP with the highest priority is dialed first. If the device is unable to log in to the ISP account with the highest priority, it dials the ISP with the next highest priority number, and so on, until there are no more ISP configurations.
To create the settings for an ISP connection:
Click the Add icon in the ISP Settings area of the Modem configuration screen.
Specify the name for the ISP setting.
Specify the login name and password for the ISP account.
All passwords handled by NSM are case-sensitive.
Specify the primary phone number and optionally, an alternate phone number. If the modem uses pulse dial by default but you want to use tone dial, precede the phone number with a T. If the modem uses tone dial by default but you want to use pulse dial, precede the phone number with a P.
Specify the priority for this setting, relative to other configured ISP settings. The highest priority is 1.
