Overview
Note: If you're using a router
the information below is not relevant.
Enternet
is the PPPoE client software generally supplied by ADSL
ISPs to their customers. It is not designed for, and does not
work for Cable Broadband connections.
RASPPPoE
is an alternate, freeware PPPoE client that many people find easier
to use and preferable when ICS is to be installed. See the RASPPPoE
guide for more on this alternative.
To share an ADSL Internet connection using Windows 2000 built
in Internet Connection Sharing, you'll need a PC to act as a Server
to handle the incoming connection and to distribute that to the
other computer/s.
The Server will need two Network cards. One to connect to the
Modem and one to connect to the internal network.
If you're just connecting to one other PC without a hub, you can
only achieve that by using a crossover cable. If you're connecting
via a hub or switch, you'll need to use a standard, straight through
cable as the hub provides the crossover.
Older coaxial Networks are exactly the same to configure in principal.
Note:
ADSL uses Point to Point over Ethernet, not Ethernet, so it's
possible to get away a single NIC in the Server by plugging the
modem straight into a hub. You'll need a 10 or 10/100 hub (It
won't work in a 100 base hub) and plug it into the uplink port.
If you don't have an uplink port, or it's already used, you'll
need a crossover cable.
Configuring a Server or Stand Alone PC
We'll start by configuring the NIC
for the modem. Once it’s physically fitted and the drivers are
installed, plug the modem in.
What we're going to do here, you might find a little unusual
at first. We're going to assign a static IP
address to this Network card. Yep, that’s right! The reason for
this is that ADSL uses Point to Point over Ethernet and not Ethernet.
This means that the TCP/IP on the NIC isn't used. Assigning a
static IP will stop the PC trying to find one on start up and
while it's running, which can cause it to run slower than necessary.
If you're plugging the modem directly into a hub without a second
Network Card, then use 192.168.0.1 instead of 10.0.0.3 on the
adaptor.
Warning:
Make sure you don't inadvertently put a static IP address on the
NTS Telesystems adaptor once it's installed. That'll stop your
Internet Connection.
Go to your "Control Panel"
Choose "Network and Dial-Up Connections" 
Right-click and select Properties of the Adaptor plugged
into the modem
Select properties of TCP/IP
Tick "Use the following IP
Address" and give it any internal IP
(suggest 10.0.0.3) 
Set the subnet mask to
255.0.0.0 
“OK”
Don't restart if prompted. We can install the Enternet software
first.
Stop any running tasks, particularly Cleansweep and stick the
installation CD in. Follow your nose and restart when it prompts
you to. Later you'll need to create a profile in the folder that
appears on the desktop to make the actual Internet connection.
Just open the folder and click on "create profile".
Note: Do not tick the box to enable it to connect automatically
at startup unless you update to at least version 1.4.
Do
not choose the option to update Internet Explorer. It is a
customised version which will configure outdated proxy details
and stop your browser from working.
On reboot, go back into Network & Dial-Up Connections
and Right-click the NTS PPPOE adapter.
Click properties and UN-tick everything except TCP/IP
Select TCP/IP Properties and ensure it's all set to automatic

Select "advanced"
Select WINs and disable NetBios over TCP
Select “DNS”
In DNS Suffix, BigPond users* type vic.bigpond.net.au 
“OK”
And restart if prompted.
*
Other Broadband users will need to consult their ISP for these
details. Often they're mentioned in on-line FAQs.
That's it for a stand alone PC. Continue ahead for Networking.
These
principals will generally apply to any NAT based solution like
Sygate, Winroute and Win2K Server's NAT application as well as
ICS.
Now for the other Network Card
As above, go to your "Control Panel"
Choose Network & Dial-Up Connections
Right-click the network card which is connected to your LAN.
Click "Properties"
Give it a static IP of 192.168.0.1
Set the subnet mask to
255.255.255.0
Note:
For the Computers to all "see" each other in Network
Neighbourhood, otherwise known as "My Network Places",
ensure file & printer sharing is active on this card
and Enable Netbios over TCP under the WINs tab.
Windows 2000 ICS
Enable sharing on the Network Telesystems PPPoE adaptor.
Go to Network & Dial-Up Connections in Control Panel
Right-Click the Network Telesystems Adaptor, select properties
and open the sharing tab. It's self explanatory from there.
Client Configuration
Go to your Control Panel
Choose "Network and Dial-Up Connections" 
Right-click and select Properties of the Adaptor plugged
your hub or other PC
Select properties of TCP/IP
Ensure everything is set to Automatic 
“DNS” as below *
“OK”
Restart if prompted.
* Telstra users: Just add "vic.bigpond.net.au"
as a domain suffix as well as "bigpond.net.au" to all the client
PCs. win98/ME .
Win2K .
* Other Broadband users will need to consult
their ISP for these details. Often they're mentioned in on-line
FAQs.
For email: Just put your mail server's name in the SMTP
field in the relevant email address properties. In Outlook Express,
it should look like this for BigPond users. 
You will need to do this whether your email account
is with your Broadband ISP or not. Any replies will come to you
via your usual mail server. So it'll use your ISP’s to send and
the other to receive. Your contacts won't know the difference.
Note:
If you want static IPs
on the LAN, you'll need to install the server's
IP address as a gateway on the client
PCs and also as a DNS search order. 
This is also often a good method to get around some inexplicable
difficulties.
Note:
For the Computers to all "see" each other in Network
Neighbourhood, otherwise known as "My Network Places",
ensure file & printer sharing is active on this card.
Tweaking MTU
Using NAT applications like ICS
or Winroute
with ADSL usually will mean you’ll
be able to ping websites on the
client PCs but won’t be able
to access them with your browser, although some sites like microsoft.com
may still be accessible for some reason.
This is a problem caused by nonstandard MTU
settings that are particular to ADSL.
There are several ways around this. The easiest way is to download
the latest version of Drtcp
and set it as below on the clients
–

Then click “apply” and “exit” and reboot and you should be away.
Adjusting
MTU can also be done manually using
regedit. More info on this and applications for Macs here.
