Finding an Internet service provider
Internet access is available from Internet Service Providers (ISPs). Typically, there are several ISPs in each
area. To locate ISPs in your area, consult your telephone book, local computer magazines, the business section
of a local newspaper, or the following URL on the Internet: ‘http://thelist.internet.com’. Also see Netopia’s
home page at ‘http://www.netopia.com’ for a list of ISPs with special programs and promotions for Netopia
customers.
You could select a cable television company that offers cable modem service as an ISP. Another alternative
could be a traditional ISP that partners with a Competitive Local Exchange Carrier (CLEC) telephone service
provider to provide a Digital Subscriber Line (DSL).
ISPs typically support Internet connection devices compatible with their service. So-called “cable modems” are
an example of such devices. You should choose the connection device that your chosen ISP supports, or you
could choose an ISP based on the type of device and connection you prefer.
Most most cable and DSL modems have a 10Base-T Ethernet connection port for connecting a PC. The Netopia
R9100 Ethernet Router uses this connection port to connect all the computers on your LAN to the Internet.
If your area has more than one ISP , the following considerations will help you decide which ISP is best suited for
your requirements.
Unique requirements
Make sure the ISP can meet any unique requirements you may have, such as:
■
Dynamic or static IP addressing
Custom domain name
■
■
Multiple e-mail addresses
■
Web site hosting
Pricing and support
Compare pricing, service, and technical support service among various ISPs.
2-2 User’s Reference Guide
Endorsements
Consider recommendations from colleagues and reviews in publications.
Deciding on an ISP account
Your ISP may offer various Internet access account plans. Typically, these plans vary by usage charges and the
number of host IP addresses supplied. Evaluate your networking needs and discuss them with your ISP before
deciding on a plan for your network.
The following checklist is a guide to ensure that you obtain the Internet service you require.
Setting up an account using a Netopia R9100
Check whether your ISP has the Netopia R9100 on its list of supported products that have been tested with a
particular configuration. If the ISP does not have the Netopia R9100 on such a list, describe the Netopia R9100
in as much detail as needed, so your ISP account can be optimized. As appropriate, refer your ISP to Netopia’s
Web site www.netopia.com for more information or call us at 1-800-NETOPIA. Our representative can call your
ISP and introduce them to the product. As necessary, we can provide them with the technical background they
need to support the product.
Obtaining an IP address
Typically, each network computer that requires Internet access requires its own unique IP address.
Consider expected growth in your network when deciding on the number of addresses to obtain. Alternatively,
you can use the Network Address Translation and DHCP features of SmartIP.
If some or all of your networked computers require simultaneous Internet access, and you don’t want to use
DHCP, obtain a block of IP host addresses large enough for each computer to have its own address, plus one
for the Netopia R9100.
SmartIP
The Netopia R9100 Ethernet Router supports the SmartIP™ feature, which includes Network Address
Translation.
Network Address Translation provides Internet access to the network connected to the Netopia R9100 using
only a single IP address. These routers translate between the internal or local area network (LAN) addresses
and a single external IP address, and route accordingly.
For more information on Network Address Translation, see Chapter 9, “IP Setup and Network Address
Translation.”
Obtaining information from the ISP
After your account is set up, the ISP should send you the IP parameter information that will help you configure
the Netopia R9100.
Setting Up Internet Services 2-3
Local LAN IP address information to obtain
Your ISP will need to provide you with the following information:
■
The default gateway IP address
Remote IP address
■
■
Local WAN IP address and subnet mask
■
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)
Refer to the section “Quick Easy Setup connection path” on page 7-3 for a handy worksheet.
Note:
The default gateway, WAN address and mask, DNS, and domain name are all obtainable via WAN DHCP,
if your ISP supports it.
With Network Address Translation
If you are using SmartIP (NAT), you should obtain the following:
If you are connecting 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 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, where 192.168.1.1 is the default IP address of the router.
Without Network Address Translation
If you are
not
using Network Address Translation, you will need to obtain all of the local LAN IP address
information from your ISP and you will need to pay for an IP address for each device on the network.
If you are not using SmartIP (NAT), you should obtain:
■
The Ethernet IP address for your Netopia R9100
■
The Ethernet IP subnet mask for your Netopia R9100
An IP address for each device on your network, in the same network range as the Netopia R9100.

Find a location
When choosing a location for the Netopia Router, consider:
■
Available space and ease of installation
Physical layout of the building and how to best use the physical space available for connecting your Netopia
■
Router to the LAN
■
Available wiring and jacks
■
Distance from the point of installation to the next device (length of cable or wall wiring)
Ease of access to the front of the unit for configuration and monitoring
■
■ Ease of access to the back of the unit for checking and changing cables
■ Cable length and network size limitations when expanding networks
For small networks, install the Netopia R9100 near one of the LANs. For large networks, you can install the
Netopia R9100 in a wiring closet or a central network administration site. In most cases the router will be near
the cable or DSL modem which is near the cable or DSL wall outlet. You could route a line from the wall outlet
to a wiring closet if you store the modem and router there.

Overview
You can connect the Netopia R9100 to an IP or IPX network that uses Ethernet.
If you have purchased the AppleTalk feature expansion kit, you can also connect the router to a LocalTalk
network that uses PhoneNET cabling.
Additionally, you can connect an external modem. See “Adding an external modem” on page 4-7.
Caution!
Before connecting the Netopia R9100 to any AppleTalk LANs that contain other AppleTalk routers, you should
read “Routers and seeding” on page 11-3.
See the later sections in this chapter for details on how to connect the Netopia R9100 to different types of
networks.

Readying computers on your local network
PC and Macintosh computers must have certain components installed before they can communicate through
the Netopia R9100. The following illustration shows the minimal requirements for a typical PC or Macintosh
computer.

Your PC
or Macintosh
computer
To the Netopia R9100
Application software: This is the software you use to send e-mail, browse the World Wide Web, read
newsgroups, etc. These applications may require some configuration. Examples include the Eudora e-mail client
and the Web browsers Microsoft Internet Explorer and Netscape Navigator.
TCP/IP stack: This is the software that lets your PC or Macintosh communicate using Internet protocols.
TCP/IP stacks must be configured with some of the same information you used to configure the Netopia
R9100. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a built-in
TCP/IP stack. See “Configuring TCP/IP on Windows 95, 98, or NT” on page 3-2. Macintosh computers use
either MacTCP or Open Transport. See “Configuring TCP/IP on a Macintosh Computer” on page 3-4.
Ethernet: Ethernet hardware and software drivers enable your PC or Macintosh computer to communicate on
the LAN.
EtherTalk and LocalTalk: These are AppleTalk protocols used over Ethernet.
Once the Netopia R9100 is properly configured and connected to your LAN, PC and Macintosh computers that
have their required components in place will be able to connect to the Internet or other remote IP networks.

Connecting to an Ethernet network
The Netopia R9100 supports Ethernet connections through its eight Ethernet ports. The router automatically
detects which Ethernet port is in use.
You can connect either 10Base-T or EtherWave Ethernet networks to the Netopia R9100.
The following table displays some important attributes of these types of Ethernet.

To connect your 10Base-T network to the Netopia R9100 through an Ethernet port, use a 10Base-T cable with
RJ-45 connectors.
If you have more than eight devices to connect, you can attach additional devices using either a 10Base-T hub
or an EtherWave daisy chain, or some combination of both.
If you add devices connected through a hub, connect the hub to Ethernet port number 1 on the Netopia R9100
and set the Normal/Uplink switch to Uplink.
When there are no more free ports on the 10Base-T hub, the network can be extended using EtherWave, a daisy-chainable
solution from Farallon.

Adding an external modem
You may want to add an external modem to your Auxiliary port. Remote modem terminal emulator setups can
dial in to the modem line and establish a remote console session. This allows Netopia Inc.'s “Up and Running,
Guaranteed!” department or other administrator with the appropriate security to remotely configure your router
for you.
Obtain the special external DB-25 modem cable (Netopia P/N TE6/DB25) either from your reseller or directly
from Netopia.

By default, the Auxiliary port on your Netopia R9100 is enabled for remote console configuration via an
external asynchronous modem. This means that all you have to do is connect your modem to the Auxiliary port
and configure its settings in the Line Configuration screens under the WAN Configuration menu.
Full Auxiliary Port PPP capabilities can be enabled on a Netopia R9100 as an upgrade option.
For pinout information on the HD-15 to DB-25 modem cable, see “Pinouts for Auxiliary port modem cable,” in
Appendix F, “Technical Specifications and Safety Information.”

Connecting to a LocalTalk network
If you have purchased the AppleTalk feature expansion kit, you can also connect the router to an AppleTalk
network that uses either Ethernet or LocalTalk. Refer to the sheet of optional feature set add-ons in your
Netopia R9100 documentation folio.
The AppleTalk feature expansion kit includes a dual RJ-11 PhoneNET connector that attaches to the Auxiliary
port on the Netopia R9100.

HD-15 (female)
Connect the male HD-15 end of the LocalTalk cable to the Auxiliary port on your Netopia R9100. Connect the
other end of the cable to your LocalTalk network. You can use only one connection on the Auxiliary port. You
cannot use both the PhoneNET connector and an external modem.
If your LocalTalk network is not based on standard PhoneNET cabling, use a PhoneNET-to-LocalTalk adaptor
cable available from Farallon Communications, Inc. Connect the adaptor cable’s RJ-11 connector to the
AppleTalk cable’s PhoneNET connector. Connect the cable’s mini-DIN-3 connector to your LocalTalk network.
Be sure to observe the standard rules governing maximum cable lengths and limits on the number of nodes on
a PhoneNET network. The dual RJ-11 PhoneNET connector allows insertion in the LocalT alk daisy chain or at the
end. If the device is connected at the end of the daisy chain, you must install the accompanying terminator.
