![分配静态 IP 后无法通过 SSH 访问 Debian 实例](https://linux22.com/image/102688/%E5%88%86%E9%85%8D%E9%9D%99%E6%80%81%20IP%20%E5%90%8E%E6%97%A0%E6%B3%95%E9%80%9A%E8%BF%87%20SSH%20%E8%AE%BF%E9%97%AE%20Debian%20%E5%AE%9E%E4%BE%8B.png)
我有一个将遥测数据发布到远程服务器的设备。该设备运行 Debian,到目前为止,我一直通过 WiFi 通过本地网络进行 SSH 调试。在现场,该设备将使用 4G 调制解调器,并且我已让 ISP 为设备分配静态 IP,以便进行远程故障排除。 4G 调制解调器正在工作以连接到互联网 - 我可以 ping 网站等 - 但每次我尝试通过 SSH 连接到静态 IP 时都会超时。我确定我错误配置了 /etc/dhcpcd.conf 或 /etc/network/interfaces,但我不确定是哪一个。接口是eth1
.

该问题与盒子上的网络配置无关;在过去两个月中,Verizon 制定了一项政策来阻止 M2M 设备的传入连接。如果您需要通过蜂窝连接远程访问设备,则需要与 Verizon 合作设置专用网络。
