ADSL, Microsoft 2000 Server SBS, ISA, ICS, Exchange - HELP! !

[jon_scriven]

Hi,

This is a request for advice - a bit in depth but maybe someone has
some pointers or at least is aware of some useful resources.

I have recently upgraded a small network from a peer to peer to client
server setup (at least that's what I wanted to do).

The current setup is 4 x Windows XP Pro machines, 1 x Windows 2000
server SBS (not being currently used due to these problems),Outlook
for Email and an ADSL line from one of the client machines currently
shared using Internet Connection Sharing.

* Please note, there is no more money to spend, I need a solution that
works with this setup !!

Now the ADSL is BT business 500, which I found during the server
install is not compatible with 2000 server (BT money grabbing if you
ask me - it works fine under 2000 & XP Pro) and this is the main cause
of my problems.

I installed Windows 2000 SBS so that I could get Exchange running
using POP3/SMTP (which they currently download to a PST file directly
via Outlook) - SBS version of Exchange supports POP3 - but I could get
mail in but not out.

The other thing that I wanted was to get ISA server running as a
firewall and allow VPN (access to files and OWA - the IP address is
curently dynamic but will soon be changed to static) but I fear that
not having the ADSL on the server will cause problems with this too.

Any idea's about how I can force the ADSL machine to act like a router
into and out of the company - it currently needs to run DHCP because
of the ADSL which is also not ideal. DNS is running locally on the
server.

Business 500 comes with a USB DSL Modem. We really want the machine
that is connected to ADSL to work as a router.

I want to set up ISA Server as a firewall and also use it as a VPN,
but if the static IP address relates to the ADSL connected machine and
not the Server, am not sure how (or if) this will work.

I need to have some way of making the XP ADSL box act almost like a
relay, so that data coming in (such as trying to connect to a VPN)
gets forwarded straight to the server, and all the exchange data, gets
sent straight out to the internet.

Any idea's/comments or ridicule for trying such a thing will be
appreciated!!

Can you configure ICS on the machine with ADSL? This article shows how to
point PPTP at your VPN server:

Not sure of the best plan for addressing and name resolution, but I might be
tempted to use static addressing and maybe hosts files with such a small
network...

I had a similar problem,

And fixed it using another software to connect through
the ADSL Connection which uses PPPoE(In my case), I got a
Service Acces Manager from speedstream(donloaded for
free) that was compatible with my ADSL Modem, And could
Run on Windows 2000 Server, it allowed me to create a
Demand Dial interface on RRAS (Routing and Remote Access
and used NAT to share Internet) Also works fine to VPN to
the network.

Took some time to configure correctly , But worth the
time.

RRAS has some many benefits over ICS, I really recomend
it.
