Model RT338 ISDN Router Installation Guide
Using Private IP Addresses
Using the DHCP protocol, the Model RT338 router assigns private IP addresses
to all the PCs on your LAN (when the PC reboots). The Internet Engineering
Task Force (IETF) reserves these addresses for use in private networks:
•
192.168.0.1—local IP address for the router (This address also serves as the
DNS address and default gateway address for all of the PCs.)
•
192.168.0.2 through 192.168.0.32—IP addresses of your PCs
•
255.255.255.0—subnet mask for your router and PC
Setting up an ISP
Contact an ISP and request a single-user Internet access account. You can
connect a multiuser LAN through a single-user account by using the Network
Address Translation (NAT) feature on the router.
In a single-user account, the ISP assigns one registered IP address to use. With
most accounts, this address is assigned dynamically each time you log in to the
account, so you will not need to know the actual address. The NAT feature
translates the private IP addresses of your network PC(s) to this address for
accessing the Internet.
Account Information
The ISP should give you the following information for your account:
•
Local phone number for accessing the ISP
•
Login name
•
Password
Questions to ask the ISP
In addition, you should ask your ISP these questions:
•
Will the IP address be dynamically assigned?
Refer to the Model RT338 ISDN Router Installation Guide on the Model
RT338 Resources CD for instructions to configure a static IP address.
•
Will your DNS server address be dynamically assigned?
If not, enter it in FirstGear’s ISP connection.
•
Does your ISP support Multilink Protocol?
If you want to connect both ISDN B channels simultaneously for a 128
Kbps connection, your ISP must support Multilink Protocol.
