无法正确配置Cisco-ASA 5505

Question

我已经在这2天，通过无数的论坛和教程，直到配置我的ASA-5505。我无法上网(甚至使用ASA的ping )，我无法在网络上“看到”ASA。基本上，除了控制台，它是一片死气沉沉的硬件。我的调制解调器也被设置为桥接模式。这是我遵循的教程：这里..。不知道下一步该去哪里..。“外部”vlan似乎配置错误，我已经尝试了太多的渗透，我确信我忽略了一些重要的、显而易见的东西。当我能够从ASA那里得到8.8.8.8的时候，我会很高兴的！

以下是我的Comcast设置：

链接我说，我可能错过了一些关键和明显的东西，然而，有一个开发背景，网络是一个有点外化的概念。

最近我经历了同样的阶段，没有寻找上面的配置问题，如果你不知道你在做什么，我想说3件事，并且想把ASA连接到互联网上。

1. 使用控制台连接类型http 0.0.0.0 0.0.0.0 INSIDE和http 0.0.0.0 0.0.0.0 OUTSIDE将设备恢复为默认(可能有很多错误配置)，这样就可以使用ASDM访问ASA。
2. 使用Base，您将拥有2个VLAN (一方将是internet，另一方可以是您的家庭网络侧)，默认情况下，Int F0/0将是internet端(VLAN 2)，当您进行还原时，了解每个VLAN的子网络信息。是的，对每个人来说都是不同的，你可以计算这个。
3. 使用引导类型0.0.0.0 0.0.0.0 X.X (INTERNETMODEADDRESS，下一跳)在ASA上创建默认路由
4. 在外部接口上创建访问列表规则以允许ICMP副本，如果不这样做，您的PING到8.8.8.8将无法回复您。

希望有人能帮上忙。这是我两天的发现过程。
