This parameter determines how much memory IP allocates to store packet data in the router packet queue. When this buffer space is filled, the router begins discarding packets at random from its queue.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'ForwardBufferMemory' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.

Note: Packet queue data buffers are 256 bytes in length, so the value of this parameter should be a multiple of 256. Multiple buffers are chained together for larger packets. The IP header for a packet is stored separately. This parameter is ignored and no buffers are allocated if the IP router is not enabled.

		(Default)	REG_SZ	(value not set)
		ForwardBufferMemory	REG_DWORD	0x00012200 (74240)

	HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
