Hi all,

I am absolutely, totally and completely stuck!

I can ping the static IP that I have but can not access the server behind
the router.

I am trying to set up a PPTP VPN through a Zoom X4 Router.

The machine that is going to be the VPN server (receiver computer) is behind
the router on the LAN side. It is running XP Pro. I have used the XP new
connection wizard to set up the VPN. Everything there seems ok but how can i
check?

Under User Permissions I have added the user names and a password for each
user that I am trying to allow access to the VPN. Using the instructions
from Bob Cerelli's pages (onecomputerguy.com/networking/xp_vpn_server.htm) I
have then gone to the TCP/IP Properties page and ticked the Assign TCP/IP
addresses automatically using DHCP.

Is that the wrong thing to do? In Bobs example he ticks 'Specify TCP/IP
addresses' and then adds from 192.168.2.100 to 192.168.2.150 but he then
says "Make sure the IP scheme is the same as on your server" What does that
mean?

This is where I get confused. My LAN have either IP's of 10.0.0.4 etc or the
IP is assigned Automatically The server IP I have given 10.0.0.15 so that
the router has somewhere to port to.(the 1723, 137, 138, 139 and 47 ports
have been opened in the Virtual Server Configuration page of the router and
all pointed to 10.0.0.15) The client computers (trying to access the VPN
from another location) have Dynamically assigned IP's

I have checked with the help desk of the router and everything there seems
correct. Even when I open a DMZ on the router I still can't get access. So I
have disabled the DMZ settings again on the router.

The VPN server can access the internet OK and all the machines on the LAN
can access the machine being used as the VPN Server too.

I am getting the Error 800 when access is denied but I understand that this
could mean anything. I get the same error message whether I type the correct
password or a wrong one.

I have a static IP for the router but all the client computers don't.

Please help me as I am now so frustrated and have run out of ideas.

Cheers
Lenny
 
Lenny;

I am not familiar with your router, but on my Zyxel
router, I had to configure under "SUA Configuration", I
have to map the incoming port requests to the server to
receive the requests. For instance, if running a web
server, I would map port 80 to IP 10.10.1.1 server. I
don't know which port you need to map for VPN.

PPTP VPN uses TCP Port 1723 and GRE Protocol 47 traffic must also be able to be passed. In the case
of GRE Protocol 47, some routers call that "PPTP Pass Through" or "VPN Pass Through". Consult the
manufacturers support web site or users guide for help with that...

I have now changed the router to a puretek based around the conexant chip
set. I am having the same problems though. I have opened ports 1723 and 47
from with the vitual server set up page and directed them to the server ip
e.g. 10.0.0.6

Nowhere on the router set up pages does it mention PPTP pass through or VPN
pass through. The manafactures say that just the port 1723 needs to be
opened. I have done that but still nothing works.

Could it be a setting on the server computer that is causing the problem. I
have made sure that it never powers down, all firewalls are off. It does
have Norton antivirus 03 running though, would that make any difference?

Please, any thoughts are better than the none that I am stuck with now.
 
The forward needs to be to 10.0.0.15, per your first message. Also,
it there is no specific area to enable PPTP Passthrough, then the
router typically takes care of it itself.

The only other suggestion is to go to the client computer VPN
connection information, select its properties, click on the Networking
Tab and select PPTP (instead Automatic) in Type of VPN. It may only
be trying to make an IPSEC connection, which does not work without
much help in a NAT environment.

thanks for the reply's. I have sorted the first part out
and I feel a right dick but it was just a matter of
configuring zone alarm.

Now I need to map a network drive through the VPN and I
cann't seem to get that to work. I can see all the
folders and files through the search page but when it
comes to mapping am unable to find the VPN server.
