PPTP VPN WINDOWS XP pro SP2

[mheuvelm]

Hi,

I am trying to make a connection by Windows VPN (pptp) thru the new FireWall
from sp2 of XP from my home to the server on my work.

Fact:
When disabling the FW: all =OK

When enabling the FW and adding the 1723 TCP port it will not pass the
Username/password screen.

How do I configure the FW?

Thanks,.

Regards,

Michel.

I am having the same problem. This has been an ongoing problem. Take a
look in the microsoft.public.windows.networking.firewall newsgroup for
more discussion. The thread is titled "VPN Fails After XP SP2."

Strange! When editing the registry I came to a strange …

When changing the value on:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\S haredAccess\Parameters\FirewallPolicy\StandardProf ile\GloballyOpenPorts\List]
,-22007"
,-22008"
,-22004"
,-22005"
,-22001"
,-22002"
"1723:TCP"="1723:TCP:*:Enabled:PPTP"

change "1723:TCP"="1723:TCP:*:Enabled:PPTP"

to "1724:TCP"="1724:TCP:*:Enabled:PPTP"

and back to the correct setting "1723:TCP"="1723:TCP:*:Enabled:PPTP"

Doing this and I can connect 1 time only, changing again each time, and i
connect only 1 time?

Anybody have a suggestion? I you ask me nobody at MS tested this FW using
PPTP….?

The problem I see is different. I have 1723:TCP open, but I still cannot =

connect. There are no other firewalss or routers involved. As soon as I=20
turn off ICF, it works fine. The really odd part is that if I try to=20
connect, press the cancel button while it is trying to connect, and then =

try to connect again, it works every time.

Doesn't work for me...? Why?
