PPTP VPN 1841 Router

All,

I am trying to provide remote users access to my network. I have a single router with a public IP address that then NATs to a class B internal address scheme. I would like it so that users can use Microsoft's VPN client to connect to the router, and then assign them an address within the pool of the local network. I have followed a few guides online, but seem to be missing something. Here are the commands I issued to make it work and attached is my configuration (details omitted in some cases).

vpdn enable

vpdn-group BLACKLAB-VPN

accept-dialin

protocol pptp

virtual-template 1

exit

interface Virtual-Template1

ip unnumbered fa0/0

peer default ip address pool blacklabpool

ppp encrypt mppe auto required

ppp authentication ms-chap ms-chap-v2

ip local pool blacklabpool 10.62.1.200 10.62.1.254

username test password 0 test

aaa new-model

aaa authentication ppp default local

One this i noticed was your vpn was pointed at the wrong network. You have this in your config:

interface Virtual-Template1

ip unnumbered FastEthernet0/0

It should be:

interface Virtual-Template1

ip unnumbered FastEthernet0/0/2

That may fix you up. Give it a try.

I gave that a shot, but I still can't connect to it. Honestly what I am looking for is a way where my clients (Vista/XP/Linux) can connect to the VPN and get remote access without having a Cisco client. My company paid for our Cisco devices, but there is so much issues with associating that with our account. It makes it extremely difficult to actually get the client. Do you know of a way to get a VPN setup to work on this router without a client?
