I'm in VPN Hell...

[Guest]

Hello!
I've been several days trying to set up a VPN connection, unsuccesfully.
Here's the deal:
I want to connect my home LAN (2 computers, one Motorola Modem-router) to my
work LAN (10 computers, one D-Link router).
I've set up a VPN connection at work (server) and left the DHCP automatic.
I talked to my ISP at work and got them to forward all connection requests
to the D-Link Router (192.168.0.20).
I configured the d-Link router's Virtual Server Function for PPTP to the
server computer with the VPN connection (192.168.0.18).

At home, I set up a VPN connection which connects to my public IP at work
(200.114.xxx.xxx) and when I try to connect..... NOTHING HAPPENS... After a
while I get an 800 VPN error.

Could someone give me a hand?
I appreciate your help.
Thanks,
Albert C

Its possible the office router is not passing GRE Protocol 47 traffic at all
or not correctly. Some routers call that "PPTP Pass Through" or "VPN Pass
Through". Check your router manual for help. You can test this using the
PPTP Ping and VPN Traffic sections on this page...

Beyond that see Bob Lin's VPN errors page for more help....

Hello Again,
I'm not too sure about what to do in the security settings part of the VPN
configuration. Could you help me out?
Are there any particular rules regarding the users and passwords?
Thanks and Best regards,

Not that I am aware of. I limit PPTP VPN access to my home LAN to a user
with a standard account (Vista), which is synonymous to a limited account in
XP.

Hello Again again.
Ok, so I got part right, but still not everything.
I enabled port 1723 on my firewall. I read on a previous thread of yours
that this would automatically enable protocol 47?
Anyways, I ran the pptpsrv and pptpclt and I got the text part (1723) but
not the GRE Packets.
What should I do?
Best regards and thanx,
Albert C

If you can't pass GRE Protocol 47 traffic through your router then your only
choice is to upgrade the firmware in the hopes that will fix the issue or
replace the router with a device that is known to pass GRE Protocol 47
traffic correctly. Your other choice is to upgrade both routers to routers
that can act as VPN end-points. Many manufacturers make them including
Linksys, ZyXEL, etc...

Hello Again Sir.
Well, I finally got the vpn up and running... Sort of.
I got the server going at the office and the client at home.
The connection seemed to go ok.
However, I can't see my work (server) network... I have not been able to see
or access any computers there.
Where do you think I went wrong?
Thanx and Best regards,
Albert C

Presuming you have shared folders configured and you can ping the computer
the shared folder is on you need to use the computers IP or name plus share
name to access it.

Example:

\\12.34.56.78\ShareName

....or...

\\PCName\\ShareName

If you want to use the PCName you can use a "lmhosts" file to map the
computer name to its LAN IP address (static). See this article from
Microsoft for the syntax.

http://support.microsoft.com/kb/314884/en-us

The lmhosts file is resident in the "C:\Windows\system32\drivers\etc"
folder. There is an example lmhosts.sam file in that folder that you can use
as a template.

Here is an example VPN client lmhosts file based on access to this network.

http://theillustratednetwork.mvps.org/Vista/PPTP/ExampleVistaVPNNetwork.pdf

Note the use of a lmhosts file can get quite cumbersome in a large network.

Good luck...
