ISP Settings
To configure your ISP settings, you must obtain your Internet information from your dial-up Internet
Service Provider. Use the information to configure the following dial-up ISP Settings:
1. Enter the primary number used to dial your ISP in the Primary Phone Number field.
Tip If a specific prefix is used to access an outside line, such as 9, &, or , , enter the number as part
of the primary phone number.
2. Enter the secondary number used to dial your ISP in the Secondary Phone Number field
(optional).
3. Enter your dial-up ISP user name in the User field.
4. Enter the password provided by your dial-up ISP in the Password field.
5. Confirm your dial-up ISP password in the Confirm field.
6. In the IP address section, select Obtain Automatically if you do not have a permanent dial-up IP
address from your ISP. If you have a permanent dial-up IP address from your ISP, select Specify
and enter the IP address in the IP Address field.
Alert Do not enter your broadband/high speed ISP information here. Enter only your dial-up Internet
access information.
7. If you obtain an IP address automatically for your DNS server(s), select Obtain Automatically. If
your ISP has a specific IP address for the DNS server(s), select Specify and enter the IP address
in the field. Alternatively, you can use your internal DNS server IP address or a specific DNS
server IP address on the Internet.
8. If your ISP has given you a script that runs when you access your ISP connection, cut and paste
the script text in the Chat Script field. See the Information on Chat Scripts section at the end of
this chapter for more information on using chat scripts.
Location Settings
Use this section to configure modem behavior on the TELE3 SP for WAN failover. The TELE3 SP has
an autodetect feature that detects when the WAN Ethernet cable is physically disconnected from
the TELE3 SP and automatically dials the ISP whether or not Enable WAN Failover is selected. You
can override this feature by selecting Manual Dial for the modem behavior. There are three types of
dial-up behavior:
•Persistent Connection - By selecting Persistent Connection, the modem dials automatically
when a WAN connection fails. If the Primary Profile cannot connect, the modem uses the
Secondary Profile to dial an ISP.
•Dial on Data - Using Dial on Data requires that outbound data is detected before the modem
dials the ISP. Outbound data does not need to originate from computers on the LAN, but can
also be packets generated by the SonicWALLTELE3 SP internal applications such as
AutoUpdate and Anti-Virus. Also, if Enable WAN Failover is selected, 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 Secondary Profile to dial an ISP.
