I have been trying to setup an VPN connection between two personal
computers. One is my sons and one is mine. I have setup windows to
accept incoming connections, so that it lets VPN connections to be
made. then with his PC i have put my Public IP address the one given to
me by the ISP and tried to connect but everytime i try it just says
that the host is unreachable and wheather i want to redial. The user
account that i am using to logon with is the same at both ends. I am
using a Netgear DG834GT Router. I have checked my log and it shows that
nothing has tried to connect to me. I have pinged my router and it
works. So the Router is on the internet but either he router is not
routing the messages. I have looked for Port forwarding for the router
and the router does not need to be setup in this way becuase it
automatically lets VPN connections through. Can anyone help me?

It sounds like your trying to use the built-in PPTP VPN server and client
for XP. If that's the case you need to forward TCP Port 1723 on the router
the server PC is behind and make sure the router also passes GRE Protocol 47
traffic. The latter is sometimes called "PPTP Pass Through" or "VPN Pass
Through" depending on the manufacturer of the router. Note that some
consumer grade routers have issues with GRE Protocol 47 traffic. You can
test this using the "PPTP Ping" and "VPN Traffic" sections on this page..

If you can't get GRE Protocol 47 traffic through your router you might look
at using Secure Shell (SSH) and WinSCP as an alternative for an encrypted,
safe and secure way to access files remotely...

to the computer. But i have a new error code 733.
What is this and how do i solve this problem

Thanx for the link. I have mange to sort most the problems out but one.
When i try to connect to the client computers or even if the client
connects to the server and try to access the shared areas using
explorer in \\server\sharedarea format it does not connect and does not
list the other computer in the workgroup computers. I dont know
wheather it is supposed to but i know it should let the users access
the other computers shared areas

If your trying to access the server, or other PCs on the remote network, by
name you may need to use a lmhosts or hosts file to map names to LAN IP
addresses. Here is an example lmhosts file which is based on this example
network...

Also make sure NetBIOS over TCP/IP is enabled on your machines...

I have checked and NetBIOS is probally what i causing the problem. The
client is using netbios but how can i tell that the Windows XP Pro is
using NetBIOS for the VPN.
