LAN ad DSL

We have a dozen Win 98 and XP Pro machines on a peer to peer network. Each
workstation has a static IP (10.2.3.1, 10.2.3.2, etc...) along with a couple
of printer servers. All are connected into a 10/100 switch. Each workstation
has a modem and is connected to a dial up ISP. All works fine.

I want to drop the ISP and give the workstations access to DSL.

What do I need to give 3 or 4 of the workstations access to the DSL, be safe
from virus's etc. and still keep the original LAN intact? I am assuming I
need a router? (We are on two floors so I would also assume cat 5 cable not
wireless?)

Thanks much.

Yes, you need a router, perhaps with integral firewall capabilities
(varying levels of protection are available from simple NAT all the
way to stateful packet inspection and beyond, at near-free to quite
pricey), and a DSL modem (probably provided by your ISP to ensure
compatibility). You may also need some (probably minimal) additional
cabling.

Viruses often involve some degree of "social engineering," so train
whoever is using the Internet. Since you already are connected, one
might assume you've already done some of this. One might also assume
you have something in place to ensure security patches are applied.

Rob,

Make sure you have good Anti Virus and Spyware checking procedures - a
permanently on internet will result in more of everything so the chances of
infection are greater.

I would recommend strong training as said in browsing and email use - no
broadcast "social" emails, business only usage, no downloads without
authorisation, no software installation at all, and a huge amount of
worldly-ness - being aware of all the pitfalls from phishing to spam and so
on. IE keep things hygenic.

From your description, it sounds like you are already networked, presumably
with CAT5 and probably all going through a hub?

If so, you can just add a hardware NAT device and connect the DSL in as
another node on the network. I suggest that you look at the D-Link DI-604.
It is very easy to integrate into a system. You will want to change all the
clients to use DHCP which the D-Link will do for you. Configure the D-Link
to provide addresses in the range that you desire. You can even do reserved
addressing if there are certain workstations that you have to have the same
address for. (i.e.: You have some scipts that expect a certain IP address or
something.)

The whole thing sounds much more complicated to explain than it actually is
to set up. Good Luck.
