Setting Up Internet Services D-3
Obtaining information from the ISP
After your account is set up, the ISP should send you the IP parameter information that will help you to configure
the Netopia R3100.
Local LAN IP address information to obtain
With Network Address Translation
If you are using SmartIP (NAT), you should obtain the following:
■ If you are dialing out to a remote site using Network Address Translation on your router, your provider will
not define the IP address information on your local LAN. You can define this information based on
parameters defined by another connection profile such as that to a corporate network, or an IP
configuration that may already be in place for the existing network. Alternatively, you can use the default IP
address range used by the router.
■ Primary and Secondary Domain Name Server (DNS) IP Addresses
■ Domain Name (usually the same as the ISP’s domain name unless you have registered for your own
individual domain name)
Remote WAN IP address information to obtain
■ Telephone number of the ISP’s local or nearby dial-up POP (point-of-presence).
■ PPP authentication type for router at the ISP, such as PAP.
■ Send and receive User Login name and Send and receive User Password if PAP or CHAP security
authentication is used
Without Network Address Translation
If you are not using SmartIP (NAT), you should obtain:
■ The number of Ethernet IP host addresses available with your account and the first usable IP host address
in the address block
■ The Ethernet IP address for your Netopia R3100
■ The Ethernet IP subnet mask address for your Netopia R3100
■ The Default Gateway IP Address (same as Remote IP Address in most cases)
■ Primary and Secondary Domain Name Server IP Addresses
■ Domain Name (usually the same as the ISP’s domain name unless you have registered for your own
individual domain name)
Note: If you are not using Network Address Translation, you will need to obtain all of the Local LAN IP address
information from your ISP.
