摘要： According to an example, to access a surveillance network through a Layer 2 Tunnel Protocol (L2TP) includes a private network IP address is assigned to a public network user device, and a route of a surveillance segment is transmitted to the public network user device, such that, after the route of the surveillance segment is received by the public network user device, an IP address of the L2TP virtual interface of the public network user device is configured as a next-hop of the route. When an access request to a surveillance device in the private network is initiated, a routing table of the public network user device is searched to find a matching route of the surveillance segment according to an IP address of the surveillance device. The access request is transmitted to an L2TP server through the L2TP virtual interface, and forwarded to the surveillance device.
摘要翻译：根据一个示例，通过二层隧道协议（L2TP）访问监控网络包括一个专用网络IP地址被分配给一个公共网络用户设备，并且一个监控段的路由被传送到公共网络用户设备，使得在公共网络用户设备接收到监视分段的路由之后，公网用户设备的L2TP虚拟接口的IP地址被配置为该路由的下一跳。当发起对专用网络中的监控设备的访问请求时，搜索公网用户设备的路由表，根据监控设备的IP地址查找监控段的匹配路由。接入请求通过L2TP虚拟接口传输到L2TP服务器，并转发给监控设备。
