Page 420 (Chapter 22: Remote Access Service and the Internet) of the Windows NT version 3.5 Resource Kit Networking Guide states the following concerning the DisableOtherSrcPackets registry entry:

  Since the packets that come from LAN clients are not originating from the RAS computer, you must set DisableOtherSrcPacket to 1 so  the header sent over the PPP link retains the IP address of the LAN clients.

This is incorrect. In order for the header sent over the PPP link to retain the LAN client IP address, you must set the DisableOtherSrcPackets value to 0. The default value is 1.

Also note that the text refers to DisableOtherSrcPacket (singular). The correct entry is DisableOtherSrcPackets (plural).

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

 Start Registry Editor (Regedt32.exe). Go to the following key:

HKEY_LOCAL_MACHINE\

System\CurrentControlSet\Services\RasArp\Parameters

 From the Edit menu, click Add Value. Enter the following value:

Value name: DisableOtherSrcPackets

Value Type: REG_DWORD

Range: Boolean (0 or 1)

Default: 1 (not in Registry)

 Exit Registry Editor.

NOTE: This change to the Windows NT registry requires the computer to be restarted to take effect. Do not restart the computer right now, though, because there are some additional settings that must be changed.
