Module Name:
|
||
|
|
|
||
|
|
natconn.h
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This module contains declarations for the NAT's RAS connection management.
|
||
|
|
Outgoing RAS client connections may be shared by associating them with
|
||
|
|
a router-interface of type ROUTER_IF_TYPE_HOME_ROUTER.
|
||
|
|
When such a connection is established by the user, we detect the connection
|
||
|
|
and create a corresponding NAT interface with the kernel-mode translator.
