Hi all,

I am absolutely, totally and completly 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 (reciever 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
