Re: VPN Connects But Connect Ping Clients or Server

Hello Len,

Thank you for posting here. And thanks for Joe's inputs.

According to your description, I understand that you can not ping SBS and
internal client from external VPN client. If I have misunderstood the
problem, please don't hesitate to let me know.

Based on my research, I suggest we try the following steps to see if we can
resolve this issue:

To resolve this problem immediately, contact Microsoft Product Support
Services to obtain the hotfix: KB897651

For a complete list of Microsoft Product Support Services telephone numbers
and information about support costs, visit the following Microsoft Web
site:
http://support.microsoft.com/contactus/?ws=support

Note: This hotfix will update file ipnat.sys automatic. You must restart
the computer after you apply this hotfix.

After you install this hotfix, you must set the value for the following
registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IpNat\Parameters
You must set this value as follows:
Value name: DisableBootTimeSecurity
Value type: REG_DWORD
Value data: 1

I would like to suggest you re-run the CEICW Wizard. Open Server Management
console and navigate to 'To Do List'. Click 'Connect to the Internet' and
you will see the wizard. More info:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

Open Routing and Remote Access console. Right-click the Server Name and
choose 'Disable Routing and Remote Access' option. This option will remove
all current RRAS configurations and stop the service. After doing this,
open Server Management console and navigate to 'Internet and E-mail'
snap-in. Click 'Configure Remote Access' to enable the VPN service. Will
the problem be resolved?

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)
