NDIS3PKT utility commands

ndis unit
ndis3 ifn [handle]
ndisinfo [-v]
ndis3log [c | w]
mux [on | off | restart | {reset [all | port]}]
mstcp ifn [block | allow | kill]

Command ndis displays driver information for the specified unit. An NDIS3PKT unit represents a binding to a Windows network interface controller. Note that some NICs may not actually be active at the time. Such NICs will have a mode value of 4005.

An NDISWANIP device may have up to 16 SubUnits, each one representing an established RAS Connection. Full connection details for each SubUnit are displayed.

Command ndis3 displays driver information and handles for the unit associated with the specified NAT32 interface ifn. If a handle argument is specified, the handle will be released and subsequently reallocated.

Command ndisinfo displays the list of devices and MSTCP bindings known to NDIS3PKT. Argument -v displays verbose details, including the current NDIS3PKT TCP Multiplexor table.

Command ndis3log displays the NDIS3PKT log buffer. A prior ndis3log c command must be issued to copy the log buffer into NAT32.

Command ndis3log w will block until more log info is forthcoming.

Command mux displays the NDIS3PKT TCP Multiplexor Table. Additional arguments allow TCP multiplexing to be turned on or off, to restart the driver, and to reset either all Mux Table entries or only those entries with a matching local port number.

Command mstcp enables the NDIS3PKT Intermediate Mode on the specified interface ifn. In Intermediate Mode, NDIS3PKT intercepts all Windows TCP/IP traffic and will either block or allow it. If the traffic is allowed, one special case is currently processed: TCP port 1723 SYN segments invoke the connect action if an amap entry exists, and port 1723 FIN segments invoke the disconnect action for the entry. Argument kill turns off Intermediate Mode for the specified interface. When Intermediate Mode is on, the NAT32 Trace window will enable the MSTCP checkbox and all Windows TCP/IP traffic can then be traced.

Version 3 of the NDIS3PKT driver supports a Mux Table size of 4096 entries.
