Debian                                          February 19, 2001                                    NG_SPLIT(4)

       This node type supports only the generic control messages.

       The  split  node type is used to split a bidirectional stream of packets into two separate unidirectional
       streams of packets.

       The ng_split node type was implemented in FreeBSD 3.5 but incorporated into FreeBSD in FreeBSD 5.0.

       This node type supports the following three hooks:

       in     Packets received on in are forwarded to mixed.

       out    Packets received on out will be discarded as illegal.

       mixed  Packets received on mixed are forwarded to out.

netgraph(4), ngctl(8)

       This node shuts down upon receipt of a  NGM_SHUTDOWN  control  message,  or  when  all  hooks  have  been
       disconnected.
