问题描述：

现场原架构是网关、出口、VPN、DHCP等三层配置都跑在路由器上的，原环境一切正常，需在路由器下面增加一台防火墙做二层透传，以及增加一台交换机，但增加防火墙后，客户端上网正常，但是与分支的VPN业务不正常，出现了分支可访问总部，总部访问不到分支的情况。

组网及组网描述：

组网：路由器配置一直在使用的一切正常，更改切换后网关 VPN等配置都跑在路由器上，不变，只增加一台二层透明模式防火墙，以及一台交换机，交换机配置为一个管理地址，以及默认路由，上行24口为trunk。

(附带我的防火墙配置)

10小时前提问

理论上纯二层防火墙+放行策略不会对业务进行拦截，试试跳过防火墙，路由器直连交换机试试

好的好的我尝试下

此配置为我的防火墙配置：
