Re: A second subnet

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Thanks Doug for your response, that seems a bit more straigtforward.

Just a couple of other questions I need to confirm.

1) I gather I will have to disable DHCP on the 2nd router and give the
laptops a static ip.
2) I've never used the XP SP2 firewall to prevent client machines from
accessing an existing network. How is this configured?
3) Finally, with regards the linksys access point and your previous response:-

"It doesn't matter. Unless you put the laptops on the same subnet as
existing machines they will not have access to anything except themselves
because the Linksys device is not a router."

So basically, leaving the linksys default settings as they are will not give
the laptops access to the internet because the default gateway would be on
another subnet. In order to connect the laptops to the internet I would have
to put the linksys on the same subnet as the existing network?

If this is so, can I not just go ahead and do that, and configure the XP SP2
firewall settings on the laptops to prevent access to the existing network
resources?

Many thanks Doug for all your help

Depends on the feature set of the router - probably not.

It doesn't matter. Unless you put the laptops on the same subnet as

You do not have a "2nd router" - you need to get one. Connect the router's
WAN/Internet port to a LAN port on your present router (this is not the
DWL-2000AP ). Make sure the router's LAN settings are for a different
subnet. If you have a Windows domain, domain clients must point to the DC
for DNS. You can use the XP SP2 firewall to prevent access to existing
machines from the machines connecting through the new router.

Many thanks for your reply, although a little vague.

Ok. I believe that the initial access point (the d-link), is connected to
a
router. So can this router be configured to refuse the new users laptops
access to the existing network resources, but still allow them access to
the
internet, with the linksys installed?

Are you saying that if I install the 2nd access point (the linksys), that
the laptops have to be given static ips, but cannot be prevented access to
the network resources.

Forgive me but I say a little vague, because you didn't mention how to
configure or set up a 2nd router to allow me to accomplish what I have
been
asked to do, that is, if I choose to install a 2nd router, which I believe
is
what you mean.

I have yet to find any forums that have been able to answer this question,
as to whether I use a 2nd access point or a 2nd router, and how to
configure
the appropriate device to prevent new users from accessing the existing
users
network.

I guess this question appears harder to answer than I assumed!

Many thanks
Jason

You need some kind of router to accomplish this. Both the DLink and
Linksys
devices are access points; they are not DHCP servers; and by themselves,
they cannot do what you want.

Hi

I have to setup a new mobile classroom for users with laptops, who
only
need
access to the Internet.

The current setup of this company I believe is as follows:-

They are running Windows Server 2003 with 11 wireless PCs. They have a
D-Link DWL-2000AP connected for the wireless clients. I know that the
default
ip address of the DWL-2000AP is set to 192.168.0.50.

What I don't know is whether the server or router is dishing out DHCP.
I
ASSUME the server is set to static and the d-link is dishing out DHCP.

Anyway, the new mobile classroom needs to be put on a second subnet. I
have
been given a Linksys WAP54G (wireless access point), which has a
default
ip
address of 192.168.1.254.

I need to connect the new laptop users to the current wireless
printers,
but
prevent them from accessing the current users network resources. The
new
users only need internet access.

I wondered which is the best way to set this up. I assume I can leave
the
default ip settings in place for the new linksys AP. Would I be best
to
give
the new laptops dhcp or static ips?

Also, what is the best way to configure it so that they can take their
laptops home as well and access the internet?

So to recap:-

1) new users need only internet access at work but not access to the
existing network resources.
2) They need to be able to access the internet at home as well.

All help really appreciated,

Kind regards,
Jason
