Is is possible to connect 2 ISP networks using VPN

[Guest]

Hi all...

I have an office with a small LAN connected to Internet through ISP A. The
IP assigned to the server that serves the LAN is static. That server has 2
NICs.. one connected to the Internet modem and the other to the LAN. The
server has Windows Server 2003 configured with ICS and ICF to bring Internet
connectivity to LAN PC's.

On the other hand, I have a Windows XP PC at home, connected to Internet
through a DSL connection provided by ISP B.

Is it possible to configure the Windows Server 2003 machine at the office as
a VPN and Remote access so that my computer at home could connect to it and
transparently belong to the same network? (for example, to be able to share
information between my PC at home with any PC at the office as if they were
on the same network) Of course, by authenticating in some manner before.

Thanks in advance
Jaime

Yes it is possible. But while the Server's external NIC is set for VPN use
it won't do anything else. So only your home XP and the Office server would
be connected with no Public Internet for either machine or the rest of the
office network.
When a NIC is set to VPN use all it can do is VPNs. Remember the P stands
for Private, No public access here.
I assume this is not what you're after.
You would need another Static IP (and NIC) for the users to VPN in to your
system.

I have three devices listening for incomming VPN (one hardware, two are
Servers),...they are also used for tons of other things. The fact that it
listens for VPN connection has no effect on anything else.

So.. how can I connect from my PC at home to a PC at the office LAN? For
example, if the PC at the Office has the private IP 192.168.0.2 I think I
need something to connect to it as if my computer at home were part of the
same network.

Thanks

OK we need to get a few things straight.
You would use the Internet (Public) side of your Office LAN for the VPN
connection. That is the connection open to the Public. Then your Server
handling the VPN will assign IP, DNS, etc., all part of the Remote Access
setup. Do you use DHCP? Then that will handle the IPs.
So that your route would be: Home PC > Internet <VPN Tunnel> Internet >
Public IP > Office LAN.
At which point you can map drives, use printers, etc.,
On your server create a VPN connection and assign user rights etc. At home
create a new Dialup connection using VPN, give it your Office Static IP.
Connect to the Internet, Dial the VPN, Office server assigns Private IP
(etc.) for your Office LAN.

Check the Documentation for your Systems. And give it a try, you will learn
a lot. Good Luck.
