I can make the connection now, but that is it, I can't go any further, how
can I access my files? Thank You

You would now acess files in the same way as you would if you were on
the same LAN (except you can't browse or use network neighborhood).
Specify \\IPADDRESS\SHARENAME or \\SERVERNAME\SHARENAME

I am trying to set up a vpn connection between my home (laptop dynamic IP)
and my office (pc static IP). Both machines are running windows xp pro sp2.
The office machine is behind a Linksys router and has port forwarding to the
if address of the PC enabled. Windows firewall is configured to allow VPN
and rdc and indeed I can connect no problem using RDC. When I try to
establish a vpn I get as far as logon name and password veryfication and then
everything stops. I have a feeling it may be something to do with
authentication prorocols but I don't know enough about how to configure
IPsec/certificates/MS-Chaps v2 blah blah blah. Any ideas anybody

Are you trying to make a VPN with PPTP or with L2TP?

Which ports are forwarded? The required ports are different depending on
whether you are trying PPTP or L2TP. For PPTP you need to forward TCP port
1723, plus IP protocol number 47 (known as GRE). On a Linksys, forwarding
GRE is usually enabled by enabling "PPTP pass-through". However, depending
on which model of Linksys router you have, PPTP pass-though is broken on
certain firmware versions, and incoming PPTP connections cannot be made.

With L2TP/IPSec, you need to forward UDP ports 1701, 500, and 4500, and
enable "L2TP pass-through". But setting up an L2TP server is non-trivial on
the IPSec side.

If you are trying L2TP/IPSec, then see
http://support.microsoft.com/default...b;en-us;885407 because your
L2TP server is behind a NAT router.

Hi Robin,

Thanks for your response.

These are the ports that I have forwarded in the linksys router:

PPTP 1723 TCP protocol
RDC 3389 Both (TCP/UDP) protocol
GRE 47 Both (TCP/UDP) protocol
IPsec 50 Both (TCP/UDP) protocol
L2TP 500 Both (TCP/UDP) protocol

All these ports are listed as exceptions within the Windows Firewall setup.

If you want you could have a look at the setup for yourself through RDC.

Hope this makes sense to you.

Kind regards

John Marzano

What error message are you getting?
Are you using a dynamic dns service?

Hi Jack,
I'm not using a dynamic dns service on the vpn server, it has a static IP
but the client computer (laptop) is dynamic.

Also I'm not getting an error message as such, what happens is I get a
message saying "veryfying user name and password" which just sits there until
I get frustrated with it and click cancel.

I use the same username and password to connect using RDC without any
problem at all.
