Please help...Beginner VPN Setup Questions

Hello,

I'm a complete beginner when it comes to networking, and I was just
trying to figure out how to do the following:

My DSL provider provides us with 4 static IP addresses and we would
like to share this connection between two separate networks. This
would mean that I would connect my DSL modem to my router and then
connect two routers (call them router A and router B) for networks A
and B respectively (as I would like to keep the two networks separate
and not have any computers on network A see any computers on network
B).

I was thinking about setting up a VPN so that I will be able to grab
files off our Windows 2003 Server while I'm at home.

Can you guys please tell me what is the most simple, painless way to
get this going?

I have four static IP addresses, but I'm not sure how I can assign one
of those IP addresses to go to our Windows 2003 Server (which has a
private IP of 192.168.1.10), so that a public IP address will direct
me to my Windows 2003 Server.

Does having a subnet (routers connected to routers, as described
above) make any difference as to how I set up the VPN? Is it more
difficult? If so, can you please tell me how I can set it up?

I'm really not sure what having four static IP addresses will make as
opposed to having just one. Can you guys please explain?

Sorry for all the questions, as I'm still a beginner at this

Thanks it advance! I really appreciate it!

Depends on the router. If these are Cable/DSL Routers, then these aren't
*real* routers, they are simply "Internet NAT Applicances". It is
unfortunate that the "SOHO" industry has butchered the dictionary in how
thay named these things and thereby causing a lot of confusion for people
who don't have the background to know the difference.

I'll try to keep it simple,...so let's forget about VPN right now and just
deal with the two networks. VPN will not be painless or simple, especially
if you aren't already familiar with "normal" networking yet.

1. Use just *one* DSL/Cable Router and place it between the Modem and the
1st "network". Disable the DHCP features of it and don't use them. You will
statically assign all addresses on the "1st network" for now with an address
set that is "expected" by the Cable/DSL router. You will also statically
assign the addresses on the "2nd network" as well but it must be a different
address set in a different subnet.

2. Get a *real* LAN Router, I don't care what brand but it must have at
least two Ethernet Interfaces. You could also build one using a Windows
Server machine with two NICs or the cheapest might be some old hardware
running Linux with two nics.

3. Put the LAN Router between the 1st and 2nd network.

4. Each network uses the LAN Router as the Default Gateway according to the
respective interface that faces that particular network. The LAN Router in
turn uses the Cable/DSL "Router" as it's Default Gateway.

5. The Cable/DSL router must have a way to add a "static route" to the "2nd
network" via the LAN Router as the gateway.

6. The clients will all either use the ISP's DNS directly, or they will use
the LAN Interface of the Cable/DSL router as the DNS Server and it will then
relay on to the ISP's DNS. Your exact situation may vary.

It will look like this:

Net#2--[LAN Router]--Net#1--[Cable/DSL Device]--[Modem]--Internet

you should forward the public ip ports (TCP 1723 and IP GRE 47) to a private
ip on the router. Then setup VPN on 2003 is easy. For more and other
