实施例1
本实施例中，处理模式分为以下四种：

模式2：当收到DHCP的discover包或路由器公告请求时可确认当前为局域网接入，进入IP地址分配模块给接入设备分配IP地址；
模式3：如未收到则发送DHCP发现包和路由器公告请求，待对端响应，响应正确则可确认为互联网接入，进入IP地址获取模块申请配置本端IP地址；
模式4：用户自定义的其他网络连接方式，包括但不限于，固定IP连接，PPP拨号等；
需要说明的是，各模式处理顺序可任意改变，不影响本方法所述主体功能。
图6为本发明实施例1所述的网络接入方法流程示意图，如图6所示，该方法包括：
步骤601：侦测到物理网口已连接；
步骤602：读取用户配置信息；
步骤603：判断用户配置信息是否包含PPPOE拨号配置信息，如果是，转入步骤604；否则，转入步骤606；
步骤604:：根据配置进行PPPoE拨号；
步骤605：判断PPPoE是否成功，如果是，流程结束；否则，转入步骤606；
步骤606：发送ARP请求，启动收包定时器。
步骤607：接收数据包并解析；
步骤608：判断接收的数据包是否地址请求(DHCP发现包或路由器公告请求包)，如果是，转入步骤609；否则，转入步骤610；
步骤609：和接入客户端交互，分配内网地址，流程结束。
这里，如果接收到DHCP发现包，则完成DHCP地址分配(IPv4地址分配)交互，如果接收到路由器公告请求包，则完成IPv6地址分配交互。
步骤610：判断接收的数据包是否路由器公告，如果是，转入步骤611；否则，转入步骤612。
步骤611：发送地址申请请求，转到步骤613。
这里，即发送DHCP发现包和路由器公告请求包。
步骤612：未收到对应的IP数据包或者定时器超时，转到步骤611。
步骤613：和地址分配服务器交互获取外网地址。
这里，如PC响应DHCP发现则进行DHCP地址请求交互，如PC响应路由器公告则进行IPv6地址请求，流程结束。
需要说明的是，如果用户配置信息中设置了非PPPoE拨号的其他接入配置信息，则直接根据该接入配置信息接入网络。
需要说明的是，本发明实施例可应用于各种含有物理网口的网络设备或模块，包括但不限于，移动路由宝，无线充电宝等等。
