I am attempting to set up a VPN connection between two windows 2k servers. The server that I have named laptop was able to dial up and authenticate on the one I named DC1. DC1 has the Ip address range of 192.168.0.1 and the laptop has the Ip of 10.0.0.1. I am able to ping any Ip on the DC1 side of the connection but I cannot ping the
Laptop side ( 10.0.0.1). I am able to browse folders on the laptop side but only from the VPN server.

I figured that there was a routing problem so I created a static route on DC1 to the 10.0.0.1 in the RAS console yet
this did not help.

The IP addresses are as follows:
SERVER DC1
Internet/NIC 24.88.172.28 255.255.248.0
Lan/NIC 192.168.0.1 255.255.255.0

SERVER Laptop
Dial up adapter 192.168.0.13 255.255.255.255
Lan/NIC 10.0.0.1 255.255.255.0

Any help or suggestions would be GREATLY appreciated.
Thank you in advance.

wwreed,

While the are a lot of areas that must be checked in your setup to help determine what exactly the problem is, I would strongly suggest you visit microsoft's support pages : support.microsoft.com and do a search for vpn connections between windows 2000 servers.

Your bound to find a fair bit of information that should help you resolve the problem.

I would agree that it seems to be a routing problem. If your laptop srv connects to DC1 via dialup, then the ppp interface on laptop should 192.168.0.13.

From there, your laptop must have IP routing enabled, in order to allow packets from DC1 to be routed to the networks it is connected to - which includes the nic's IP that is 10.0.0.1:

DC1(modem)
//
(modem)laptop(nic)
DC1(192.168.0.1)--//
(192.168.0.13)laptop(10.0.0.1)

In the above diagram, the laptop's nic, which is 10.0.0.1 would be pingable only if laptop had IP routing enabled, and even then you should check the routing table to make sure the entries are correct.
