PPTP Registry Settings (Windows Embedded CE 6.0)
1/6/2010
The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.
To configure the PPTP implementation, you can set the following optional registry values on the client device.
Note
The default registry values vary depending on which Catalog items are included in your OS design. For more information, see Default Registry Settings.
The following table shows the named values for the HKEY_LOCAL_MACHINE\Comm\Pptp1\Parms key.
| Value : type | Description |
|---|---|
TcpPortNumber : REG_SHORT |
Default setting is 1723. Specifies the TCP port number of the PPTP server necessary for device connection. |
UdpPortNumber : REG_USHORT |
Default setting is 47. Specifies the UDP port to which to send UDP encapsulated tunneled packets. |
MaxWanEndpoints : REG_ULONG |
Default setting is 5. Sets the number of PPTP sessions a WAN miniport can have. |
MaxTransmit : REG_ULONG |
Default setting is 32. Sets the maximum number of outstanding send packets the PPTP WAN miniport will accept. |
InactivityIdleSeconds : REG_ULONG |

TcpDisconnectTimeout : REG_ULONG |
Default setting is 30. Specifies the length of time to wait for the peer to acknowledge a disconnect request when disconnecting a TCP connection. |
TcpConnectTimeout : REG_ULONG |
