Hi to all,

We are about to move into a new office and will be sharing office space with
another firm. I have been given the job to set up an ADSL connection which
is to be shared between the two companies on 2 separate LAN's.

Lan 1 - WinXP Pro, Win2000Pro, WinXP Home, WinME and Win2000Pro running ICS
for our dial-up ISP - currently connected via 8 port 10/100 Switch.

Lan 2 - 3 X Win98 (not networked yet)

Goal: To create 2 LAN's : Lan 1 (without the Win2000Pro with ICS), Lan 2
(Win98 X3) sharing an ADSL connection while maintaining two seperate LAN's.
ie: Lan 1 computers CANNOT see Lan 2 and vice versa

Possible?
How? ADSL Router with DHCP connected to 2 switches (1 for each Lan) and a
different workgroup name for the Lan's (Office 1, Office 2)?

Also, I will need to be able to dial-in to Lan 1 and utilise the Lan 1
shares as well as internet access. Possible? If so, how?


TIA,

Ema Nymton

It would be easy to set up a shared DSL Internet connection and set up 2
separate workgroups. However, there is no worthwhile security built into XP
home, WinME and Win98. Everyone will be able to access those computers. XP
Pro has built in robust security setup to keep unwanted computers out.
There really isn't any use in the separate switches for each LAN.
Don't understand the need to "dial in to LAN1 and utilize the LAN 1 shares
and Internet access". Internet access is obtained by the router for both
workgroups and not by any individual computer. What do you mean by LAN 1
shares????

OK. Now, I have not had *any* real experience with (nor any un-real
experience either, but that's another story) "managed switches" but a
colleague of mine made mention that these things can isolate ports.

So, an eight-port managed switch where LAN1 uses ports 1-4 and these ports
are configured as a group. LAN2 uses ports 5-7 and these ports are
configured as a group. Finally, port 8 is also a member of the two groups,
to which an inexpensive Cable/DSL router is connected. Put a print server
on the router and it's a good bet that the two businesses can also share a
printer.

I'm thinking managed switches are not cheap. But they may be less costly to
acquire and learn to configure than buying a server operating system,
upgrading the hardware on one bax to accommodate server duties, and
learning how to run a server. (Which is what I have been doing for the past
few weeks - with dismal progress.)

On one of the boxes of LAN1, you say you've got a modem. If it's XP Pro,
study up on Remote Desktop Connection. If it's not, *properly* remove the
modem from whatever box it's in, and properly install it in the XP box.
Then study up on Remote Desktop Connection.

Rather than spend on managed routers and switches I think I would get
another PC. You have
less than 10 machines all together - so it needn't be a server. I would fit
3 network cards
to this , one to ADSL (could be usb instead), and one to each network. Make
networks
a different subnet. Don't have packet forwarding turned on. Run either ICS
or some other
proxy server on this PC - possibly a mail server too there are plenty of
free POP3/SMTP ones
that should do the job. This would not allow IP access to the outside
world - and would therefore
not allow some things like ICQ, or IM to work - which may be a good thing.

O course a linux box would give you more control, including IP masquerading
and a firewall and cost
you next to nothing - but you would need the expertise to make it work.
