我目前无法从 PC 访问 Internet。任何建议或意见都将受到欢迎:)

为了诊断一个更大的问题，我将我的实验室配置缩小到了基础。- pfsense 防火墙 - 1 x 路由器：e0：192.168.10.10，e1：192.168.20.1 - 1 x PC：静态 IP 地址（连接到路由器）

我可以从 PC 对外部（74.125.224.72（又名 Google））进行 Ping、traceroute 和 telnet，但是当我打开 Web 浏览器时，系统会超时。

路由器配置：

interface Embedded-Service-Engine0/0
 no ip address
 shutdown
!

 ip address 192.168.10.10 255.255.255.0
