We have configured PPTP-VPN in two routers Cisco. Here you have our configuration:
.
!
vpdn enable
!
vpdn-group Group_VPDN
accept-dialin
protocol pptp
virtual-template 1
!
interface Virtual-Template 1
ip unnumbered ser0/0.100
peer default ip address pool VPDN-pool
ppp encrypt mppe auto
ppp authentication chap ms-chap
!
!
ip local pool VPDN-pool 192.168.30.1 192.168.30.14
!
!
ip route 0.0.0.0 0.0.0.0 Serial1/0.100
!
end
These PPTP-VPN configurations worked very well for many months, when they were using PCs running Windows 2K, and Win XP-SP1.
Since they upgraded their PCs to WinXP Service-Pack 2 our problems began. None of them can establish a PPTP-VPN connection to our routers.
During our tests we have seen we can establish VPDN connections to these routers from PCs running Win2k, Win98 and WinXP-SP1 but NEVER from Win XP-SP2 ones.
We have opened UDP 62515, TCP 10000 and TCP 4500 ports at our Win XP-SP2 ws, we have turned off the Windows Firewall but we have never established a PPTP-VPN connection from them.
Please, Could any of you give us some ideas about How to fix this problem ???
Thank You

Hello Angel, this is a config I used recently and it works with my XP with SP2 installed, please give it a try, as you will see the only difference is the last line. If this doesn't work then I think you'll need to look at the XP settings for VPN

Hi,
What error message do you get? Further, PPTP requires TCP 1723 and IP 47.

Hi, i get a 619 error at Win XP-SP2 when I try to establish my PPTP-VPN connection.
I have opened TCP 1723, what's more, I have turned off the firewall feature at my XP-SP2 PCs. But I will try with IP 47 today.
Thank you for your effort
