Hi all,

I'm looking for help on how to set up a VPN-server with Windows Server
2003
and how I could setup and use this for a WLan connection to that server.

Basically what I want to do is increase WLan security.

As far as I understand, I could achieve this if I used VPN to access the
server via WLan. So I thought I'd set up a VPN-server with Server2003
and then use a VPN connection to access that LAN-server via WLan with an
XP Home Centrino notebook.
If possible, I'd like to do this without an access point, i.e. by using
an ad hoc WLan connection between server and notebook (I've got an USB
WLan adapter plugged into the server machine right now).

So, any good internet ressources on VPN and WLan I could look at?
Or does somebody even have a little How-To at hand?

And, most of all, does anybody know, whether such a setup for _ad hoc_
WLan is possible at all?

Any help/suggestion/URL is greatly appreciated!

TIA!!!

VPN will work over any IP connection. I can assure you that you can make
a VPN connection to a server (or workstation) across an ad hoc Wlan
connection. I have done it.

Simply configure your server as a remote access server. This sets up the
WAN miniports for VPN. Then set up the client machine as a VPN client and
connect to the server's Wlan IP address.

Thanks Bill!

That raises my hopes, sounds simple indeed.

Yet somehow the connection here just can't be established. It seems like the
VPN server is not responding to the "dial-in".

What I did so far is:

1. Before setting up VPN I used to have the server's LAN card and it's WLAN
USB adapter bridged together, so the notebook could access the internet via
the server's LAN card by WLAN. Now, to set up VPN I removed the WLAN adapter
from this bridge.

2. On the server I added the remote access server role:

3. In the add-role-wizard I selected the option "remote access server (VPN)"
without NAT etc.

4. As "connection to the internet" I selected the WLAN connection.

5. Still in the wizard, I defined a fixed IP pool, not DHCP for the VPN
server.

6. Then on the notebook I created a VPN dial up connection to the server's
WLAN IP and edited the logon info and the authentication method.

Well, but when I try to connect with this dial up, after waiting some while
I always get an error "VPN server is not responding". Using Netmon I see
that there is traffic between the machines. It just seems the server does
not really pass back any data to the requesting client, as if a firewall was
active or something.

Any clues what might cause this?

Any suggestion is very much appreciated!

Thanks in advance,
Marc.

Check that there are no packet filters set on the WLan interface of the
server. Also check you do not have the personal firewall active on the
client.

Hm, firewall is disabled and as far as I can tell, there're no packet
filters active.

Guess my wireless VPN experiments will become something like a new hobby
here ;-)

But thanks very much for your input, Bill!

At least I know now that it _is_ possible to set this connection up.

Regards,
Marc.
