Quick Startup Guide
CONNECTING TO AN INTERNET SERVICE
PROVIDER
Internet Access using Network Address
Translation (NAT)
1. Connect the 10BaseT cable from the PC's network card to the
Express L128T S/T. Select TO NIC on the Express L128T S/T
back panel.
2. Go to the Configuration/Connection List menu, and then press
the right arrow key to place the cursor on the Num column.
3. Type I to insert a new Connection List entry.
4. Using the arrow keys, move the cursor over the Num column for
the inserted entry. Press Enter to place the subentries into the
right pane.
5. Set the Description to an identifiable name (i.e., ISP).
6. Go into the Authentication field and select PAP or CHAP for the
Tx Method.
7. Enter your user name and password (provided by your ISP) into
the Tx Username and Tx Password fields.
8. Move the cursor to the left pane and highlight the IP parameters.
9. Set the NAT item to Yes. This is a very important step. The
Express L128T S/T will need to translate the "fake" IP
address(es) on the PC(s) connected to the Ethernet interface to the
"real" address provided dynamically by the ISP. See IP/NAT on
page 3-16 for more details.
10. All other IP parameters should be left at their default settings.
Navigate over to the Dial Out parameters.
11. Enter the number of the location to be dialed into Number 1.
Enter Number 2 if calling another ISDN device with two phone
numbers. Otherwise, Number 2 is not required.
12. Arrow left until the message Save Connection List Changes
appears. Type y to save.
13. Go to the Configuration/IP menu and enter an IP address and
net mask into the IP Address and Subnet Mask fields. The fac-
tory default setting will work just as well (10.0.0.1, 255.255.255.0).
