我希望思科专家能够看到这一点。
我正在着手准备 CCNA 资格认证，并购买了 Cisco 877W-GA-K9 进行练习（这样我就可以实际“现场”使用它）。我已经设置了桥接组等，并设法通过无线访问我的 NAS 等。内部网络运行良好。
但是我无法访问互联网；我的意思是 CD 灯闪烁然后变为常亮，表明我已经识别并（我认为......）验证了我的线路。
但是，我没有建立 PPPoE 会话，我的 PPP 灯一直处于黑暗状态。
我搜索了互联网、思科手册和不同页面上的各种可能的配置，但似乎都不起作用。所以我希望有思科经验的人能看看我的运行配置并告诉我问题是什么。
我怀疑问题出在我的拨号器和 ATM 端口之间的连接上，很可能与错误配置的 DNS 有关，但我需要帮助。外部 IP 地址和 DNS 设置为我的 ISP 指定静态 IP 地址和主/辅助 DNS 地址（而且我不确定我已经正确设置了 DNS... 就像我说的 - 刚刚开始学习 CCNA）
请有人看看我的运行配置并提供一些建议吗？

答案1
对于任何读过这篇文章或有类似问题的人，我ppp authenticate chap从拨号器 0 中删除了该线路，它立即登录。
我现在有一个“有趣的” DNS 问题，但这是一个单独的线程！
