file sharing only on the local net?

[Ron Hardin]

How do I set up file sharing so it works only on the LAN and not
through the modem?

Ie. I have 2 laptops connected with a crossover cable for the LAN,
and share on the network for the corresponding folders.

Does that make the folders accessible through the modem as well?
(As the Dell popup advisory claims)

There's a PC-cillin firewall on, though not a windows firewall.

In the properties for the Dialup only have TCP/IP installed, no File & Print Sharing etc. The firewall should also block network traffic.

What modem??? Do you the DSL/cable modem? As long as the "connecting" PC has
a "firewall" blocking the Internet access, then you are Ok!

I have a crossover cable between 2 laptops, so that's my LAN. I believe it
uses IPX/etc, at least I checked a lot of boxes that way.

Each laptop has a modem, and when I want to connect to the internet, I dialup my ISP
from whatever laptop I'm on.

The problem is sharing (all) files should be allowed on the LAN, and forbidden
on the internet.

There's a non-microsoft firewall enabled on each laptop.

Dell warns that it's sharing all files on the internet, and the question is is
this true if the added firewall is on, and if so how to fix it.

You should configure your connection like I told you. Ignore idiots that talk about firewalls. A firewall is like a parachute, you should be asking do the bloody engines work on the plane not will my parachute work.

All that's checked is TCP/IP and QoS Packet Scheduler

What does QoS Packet Scheduler do?

Nothing 99.9% of the time. It reserves bandwith if a program requests it.

You are not sharing. You can't share without File And Print Sharing installed on that connection. You can't install this without installing Windows Client.

Even then you have to specifically select something to share.

File security
Share security
Able to share (File and Print Sharing)
Firewall

So there are 4 layers that have to allow sharing.

Perhaps you can talk about the dell thing.

So the theory is, that the warning from Dell comes from
1. Ignoring the non-MS firewall (Symantec) being on
2. Ignoring that no print/file sharing is checked in the dial-up connection

because folder sharing on the network is indeed checked on folders, and the LAN
laptops indeed see each other.

Then the conclusion is that I'm okay, right?

Yes. In your case the lack of sharing on DUN (and lack of logging in) and the firewall on DUN will prevent sharing.

Is dell speaking about your DUN. What is this Dell thing.

I bought a $399 Dell Inspiron 2200 laptop in, I guess, their closeout week.

You get popups telling you about this or that that they have discovered
that they think you need to know. I don't mind them.

The damn thing does work and was cheap.

It's a lot faster than my real machine (see the headers on this),
though I'm not nearly as agile on its keyboard as on this one.

It's hard to know what an unknown program working in an unknown way thinks. You should be right.
