Configuring PPTP (VPDN) Server On A Cisco Router

Configuring PPTP (VPDN) Server On A  Cisco Router

If you need to allow VPN access to your network from the outside world then setting your Cisco router up to be a PPTP server is an easy way to do it.

Firstly we need to enable VPDN:

vpdn enable
!
vpdn-group 1
accept-dialin
protocol pptp
virtual template 254

Now we need to create the virtual template:

interface virtual-template 254
ip unnumbered fastethernet 0/0
peer default ip address pool pptp-pool
no keepalive
ppp encrypt mppe auto
ppp authentication ms-chap ms-chapv2

Once the Virtual template has been configured we need to create the IP address pool that will be assigned to the PPTP client:

ip local pool pptp-pool 192.168.0.50 192.168.0.60

We will now need to create the username and password that will allow the PPTP client to authenticate with the router:

username pptpuser password pptppassword

Finally we need to allow PPTP through any access-lists we may have on the incoming interface by appending the configuration below:

access-list 123 permit tcp any host 94.142.65.249 eq 1723
access-list 123 permit gre any any
