Win2003 VPN Issues

G

Greg Fischer

Posted this awhile ago, but got no responses. Thought I'd
post again ...

I have a Win2003 configured behind a Linksys DSL/Cable
router. The Win2003 system has one NIC. It can connect to
the Internet fine.

Machines on the internal 192.168.1.X subnet can VPN
(PPTP) to the 2003 machine.

The Linksys is configured to port forward 47 and 1723.

When I try to setup a VPN connection from outside the
firewall, the connection is denied and the following
error shows up in the IPRouterManager.LOG file:

[1076] 14:03:40: Error adding route, Stack bit == 0

Other log files indicate that the connection is being
initiated. I have tried from various different public IP
networks.

BTW - the VPN connection sets up fine with internal
machines, so I think RRAS is installed and working fine.

Any thoughts?

On the linksys, make sure you have UDP 500 for port
triggering as well as 1723 TCP. Also, verify that VPN
passthrough is enabled. If that doesn't work, I had a
problem that was fixed by updating the firmware (on a
soho3 not a linksys). Updating the firmware gave me the
option to transverse NAT, which I assume you are using
with only 1 nic. I would definetly check into this if on
the client side you are getting to "Verifying User Name
and Password".

Just a thought...

Getting the standard 721 error at the client. From the
log files, it looks like the client is initiating the
connection per the logs, but the router error is
preventing it.

Hi Greg,

I am not Microsoft, but maybe you have the same problem as me - just check
my question and MS answer in the thread "
VPN behind Cable/DSL router - why does not work?"

What is your Linksys router firmware version? I had latest 1.45.7 and it
would not work. After I downgraded to 1.44.2z, VPN started to work.

Regards,

What you require is not port 47, but GRE, which is IP protocol 47. Port 47
(tcp or udp) has nothing to do with PPTP.

PPTP data travels through the Internet inside IP packets with GRE
headers. If anything in the path (routers, firewalls etc) blocks GRE, no
data is transferred.
