How do you connect DSL internet connection, router, desktop and laptop computer

Ismael

Hello everyone,

Does anyone know how to connect a DSL connection to a router and the router
to a laptop and desktop computer, so that both the laptop and desktop
computers can see each other (share files and other resources), while both
being able to have access to the internet and firewall protection (via
router) at the same time?

Currently I have the following:

I am using WinXP Pro on the desktop computer as well as on the laptop
computer. The desktop computer has two NIC cards. A SMC EZ NIC card
connected to my DSL high speed internet connection using a standard Cat-5
cable, while the other 3Com Etherlink NIC card on the desktop computer is
connected to the laptop using a Cat-5 crossover cable.

The above works well as I am able to share files and resources as well as
have internet connectivity on each computer.

Now that I have a router I was able to get both the laptop and desktop
computer access to the internet by connecting each computer with a standard
Cat-5 cable directly to the router and the router connected via another
Cat-5 cable to my high speed DSL connection, but I could not share files or
resources between the laptop and desktop computer. How can this (or can
this) be done without using a hub.

Thanks to all who reply,


Ismael Tena Jr.

if the router is DHCP and assigns ip to all computers, that should work. can
you ping each other? or post the results of ipconfig /all here.

Make sure you have Microsoft File and Printer Sharing installed on both
machines. You can find out if it's installed by looking at the properties
for your LAN connection from the Properties page of My Network Places.

If that's installed then you need to map a network drive. You can do this by
right clicking on My Comuter and selecting Map a Network Drive. Make sure
you turn on sharing for the folder that you want to share across the
network. For example, right click on My Documents and select Properties. In
the dialog window that comes up you'll see a tab called Sharing. In that
window you will see options to share wiht others users on the same computer
as well as Share the Folder on the Network.

Hopefully this will point you in the right direction. If not just let us
know.

Cheers

Thanks for the reply Tony. Unfortunately I can't browse the network and
therefore I can't map a network drive. I also have "Microsoft File and
Printer Sharing" installed on both machines, as well as "Share the folder on
the Network" enabled on folders that I want to share on each computer.

The following are the results of ipconfig/all and the pinging if the IP
address on each machine:

One-way ping only

If you can ping other computers and other computers can't ping your
computer, this is often caused by an improperly configured firewall
on you computer. For example, ICF should not be enabled on LAN NIC.

Robert your a genius! It worked. I checked the NIC
connection/configuration on my desktop computer and sure enough it was
firewalled, (I also inspected the laptop to see if it was firewalled and it
wasn't....ahh that's why through the laptop I was able to see the desktop
and laptop, but I could only access the laptop's resources and not the
desktop's resources in the network. Meanwhile on the desktop I could not
access anything in the network at all.

I removed the firewall on the desktop and now I can see my network. Both
computers can see each others resources and have access to the internet at
the same time. Thank you!

The router I own has two more extra ports, and I am assuming that I can
connect two additional computers to my network. Thus having all four
computers access to the internet and able to share resources among each
other, as well as have the router do all the firewall protection for my
network (since I've read that a router is better than any software based
firewall as long as my computers are clean of any Trojans, Worms, Virus
etc., nothing can get into my network. I've heard though that software
based firewalls monitor the data that is coming in as well as what is going
out to the internet). What do you think? Should I leave all of the
firewall protecting job to my router, or should I install on each computer,
a firewall software that monitors what data goes in and out of each computer
for an extra level of protection?
