Setting ISP Priority for Failover

144
Example: Configuring Modem Connections (NSM Procedure) on page 142
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.
1.
Specify the name for the ISP setting.
2.
Specify the login name and password for the ISP account.
3.
NOTE: All passwords handled by NSM are case-sensitive.
Specify the primary phone number and optionally, an alternate phone number. If the
4.
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
5.
priority is 1.
Click OK.
6.

Availability" volume in the Concepts & Examples ScreenOS Reference Guide.

When using a modem connection, a trustee administrator can manually change an ISP
priority. If a failover situation occurs, the priority assigned to an ISP indicates in what order
relative to other ISPs that a particular ISP will be contacted. The lower the value, the
higher the priority of the ISP. The trustee admin can also check the availability of an ISP
with a priority setting of zero (0).
