Two-Way DirecPC

From the WinRoute administration window proceed to settings -> interface table. You should see the DirecPC USB satellite device. Double click on this device and the properties window should appear. Under the NAT tab make sure you check the box to enable NAT for this device. Under the DirecPC tab specify that you transmit through DirecPC dialup. Note that this does not actually use any dial-up accounts, but it is a necessary setting for WinRoute to function properly with two-way DirecPC.

Increasing Throughput:

You will probably experience slow speeds and incomplete file transfers from all clients passing through WinRoute. To correct this you will need to make a registry modification that will increase the TCP receive window. To enter the registry go to the start menu -> run, then type "regedit" from the text box.

Important: This must be performed on each computer behind WinRoute.

In Windows NT/2000:

Go to the Registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Add (if it exists, edit it) an entry named "TcpWindowSize" (it is of type DWORD) in registry. Set its value to "BB80".

In Windows 95/98/ME:

Go to the Registry HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP.

Add (if it exists, edit it) an entry named "DefaultRcvWindow" (it is of type string) in registry. Set its value to "BB80".

Note: BB80 is in hexadecimal format. The decimal value is 48000.
