pppd：peer拒绝同意我们的IP地址

Question

我试图通过Telit调制解调器访问数据，该调制解调器通过USB连接到嵌入式Linux板（无网络管理器）CC3200。

我已经插入了所有需要的驱动程序，我使用PPP守护程序将此ttyACM0设备连接到ppp接口，以便我可以通过ppp接口访问网络。

两天前我能够成功连接到网络并ping google.com。 但我没有弄清楚究竟是什么使它工作，不幸的是我失去了工作设置。

现在ppp peer拒绝同意IP。

我跟着这个链接进行ppp设置：http://www.techytalk.info/manage-gsm-mobile-broadband-connections-without-network-manager-ubuntu-mint-debian/ 我试着没有验证。 我还在选项文件中添加了'nodeflate nomagic and demand'。

以下是pppd的日志：

为什么协议拒绝正在接收。如何克服它。 nodeflate不起作用。 为什么同行拒绝同意IP。在工作状态下，对等体本身建议IP范围为100.xxx.xxx.xxx。

以下是路由输出

Answer 1

得到的答复天数前。 我用的PDP CONTEX 1这就需要将2 像：

'OK' 'AT+CGDCONT=2,"IP","ispapn"' 

因为CONTEX 1被保留。
