Hello,

After I thought I configured my VPN server according to A
Technet Step-by-Step, I tried to configure a client
connection from my workplace to my win2k VPN at home, but
all I get is the following error. I am trying to deploy
VPN at a small office, but started out by using my own
server as test, but I cannot get to it. I am using
Linksys BEFSX41 VPN Firewall Router, and I have port 1723
forwarded to my server on this router. Is there anything
that I missed?

Error 800:Unable to establish the VPN connection. The VPN
server may be unreachable, or security parameters may not
be configured properly for this connection.

Ensure that GRE is not blocked by the router. GRE is not TCP based, so you
cannot use port forwarding. GRE is a protocol, just as TCP is a protocol.
TCP is IP protocol 6, UDP is IP protocol 17, GRE is IP protocol 47. You do
not forward anything. You just need to make sure that your router does not
block it. Look at the router's filter setup and look for GRE by name or by
protocol number. Or check the router manufacturer's site for info on how to
allow GRE.
