我需要一些帮助。我是使用 Cisco 路由器的新手（就我自己设置它们而言），所以如果这是我看过或不理解的简单问题，请原谅我。
我有来自考克斯的有线互联网。他们给出了下面的IP地址：
IP: 98.191.**.147
DG: 98.191.**.129
SNM 255.255.255.224
IP 地址是将路由器连接到 ISP 调制解调器的 IP 地址。在局域网方面，我有以下几点：
IP address 10.0.4.1
DG 10.0.4.254
SNM 255.255.255.0
我需要做的是取10.0.4网络并告诉它Internet在98.191.**.147网络地址处，然后通过这种方式连接到Internet。我一直在观看有关如何执行此操作的一些 YouTube 视频，但是我缺少一些东西，我无法弄清楚。
这是我迄今为止所拥有的：
我在 10 点网络上没有互联网连接。
