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?
