RE: PPTP VPN connection problems

Hello Iulian,

Thank you for kind update.

Since you want to contact your local MS support for help, I would be
appreciate and think it is a more effective ways. To obtain the phone
numbers for specific technology request please take a look at the web site
listed below.

http://support.microsoft.com/default.aspx?scid=fh;EN-US;PHONENUMBERS

If you are outside the US please see http://support.microsoft.com for
regional support phone numbers.

Additional, you can establish the VPN connection from internal client, that
means the configuration on SBS is mostly correct. I think the cause of this
issue may relate to the ADSL router. As the Joe's input, we have to enable
TPC 1723 and GRE 47 on the router. I suggestion you replace the ADSL router
with another one, and test this issue.

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)

| Hello Liu,
|
| The problem is that the VPN does not disconnect. Both ends (client and
| server) show the connection active.
| However after some idle period I can not send packets across the
connection.
| A ping to the server would result in "Request timed out".
|
| Suggestion 1: I checked and the idle time is set to "never"
|
| Suggestion 2: Both internet connections are ADSL subscriptions for
| residential, but the one for the server has a fix IP.
| I've contacted the ISP and they see no stability issues on the ADSL
| connection.
|
| Suggestion 3: Yes I used the CEICW on the SBS and I checked the KB and
| confirm that the VPN is configured properly.
|
| Suggestion 4: If I connect with the VPN client locally to the internet
| gateway (the SpeedTouch 608W) and setup a local VPN connection (the IP of
the
| external connection of the server) as you suggested I see no problems.
The
| VPN is stable for hours (I did not check more).
|
| Conclusion:
| - 1 - I am using SBS2003 standard (no ISA server).
| - 2 - I have an fix IP address for the office internet connection.
| - 3 - I use the OWA from multiple locations (PCs) and looks more stable.
| However I saw that I need to logon again after a greater idle period
(15-30
| min); and I do not know if this is an internal timeout of OWA for
security
| reason (public PC access).
| - 4 - I have this issue on multiple PC (all of them XP SP2).
| - 5 - As I said the VPN does not disconnect. It is just that the
| communication with the server blocks after some idle period. If I do a
| continuous ping to the server (ping -t sbs001) the problem disappears.
|
|
| I would like to contact the local MS support (Belgium) if posible.
| I have this SBS2003 server (Dell PowerEdge 380) since last November; it
| should be under support from MS.
|
| Best regards,
| Iulian
