Newbie question about VPN's

Hi

Im new to Windows 2003 server and I wondered if anyone could help me
configure my VPN? I have set up a small VPN for a SOHO type network as a
test and opened the appropriate ports on my router.

Now, from the remote location I can connect to the VPN and even ping the
server, but I cannot access any network shares etc. I've googled around
for answers but some sites say I need 2 network cards, other sites say 1
will do (I only have 1 at the moment) and other sites say if I can ping
the server then all is well and I should see the network shares but I don't.

Does it matter that the PC in the remote location is not part of the
domain? (it's not on a domain just on a workgroup) I also noticed that
when connected to the VPN, I lose all connections to the internet, is
there a way around this?

Thanks to anyone who can help

Regards

Matt

1. It doesn't matter you have one or two NICs.
2. The VPN client doesn't need to be a domain computers.
3. For security reason, you may not be able to access the Internet after
establish the VPN.

Assuming you can ping the VPN server, do you receive a system error if you
use this command: net view \\vpnserveripaddress? This link may help too.

You will lose Internet access from the client when you make the VPN
connection because your default route is now across the VPN link, not out to
the Internet.

Making a VPN connection gives you a point-to-point connection to the VPN
server. It is not the same thing as a LAN connction. Things like name
resolution which rely on LAN broadcasts don't work.

You should be able to ping LAN machines by their IP address, but using
names or sharing files is a bit hard. With workgroups it is even harder.
(With a domain, WINS is a big help). Your best bet is probably to put all of
the machines on the LAN which you need to contact into an LMHOSTS file on
the client.

We have a domain set up, but the computer that I'm using to VPN into the
network has never been on the domain.

Where would this LMHOSTS file live then? Is there a tutorial on writing
one anywhere?

Thanks

Matt

If you have a domain on the LAN, does it run WINS? The client doesn't
need to be a domain member to take advantage of the name servers on the LAN.
If it has the correct DNS address, you can put the domain suffix into the
client's connection properties and it can resolve names using just the
machine name. (If you do "nslookup fred" the domain suffix "mydomain.local"
or whatever will be added to the request and you should get the IP address
of the LAN machine fred). If WINS is running on the LAN the remote client
can also use that to resolve names.

LMHOSTS is really just a list of names an IP addresses. The only real
trick is to be careful how you edit it.

Also note that the computer browser service relies on LAN broadcasts,
so you can't usually use Network Places from a remote client. But if name
resolution is working you should be able to share files using net use
\\fred\shareddocs (adding the ncessary username and password).
