實現根牆（物理防火牆）和虛牆（虛擬防火牆）之間的互通，可以按照以下步驟配置：

1. **虛牆默認路由指向實牆**：在虛牆的路由配置中，將默認路由指向根牆的內網接口。這樣，虛牆上所有無明確路由的流量都會通過根牆轉發。

2. **根牆上配置回程路由**：為了確保流量從根牆返回到虛牆，需在根牆上為虛牆的網絡段配置一條靜態路由，使其指向虛牆的入口接口或中間的交換設備。這保證了從外部返回虛牆的流量能順利到達。

3. **訪問控製策略**：根據網絡安全策略，在根牆和虛牆上配置訪問控製列表（ACL）或安全策略，允許需要互通的流量雙向通過。例如，允許內網地址段與虛牆的相應地址段間的流量。

4. **NAT配置（可選）**：如果存在地址轉換（如私網訪問公網），在根牆上配置NAT規則，使虛牆和外部網絡的流量可以正常轉換。

5. **網絡測試**：配置完成後，測試從虛牆到外部網絡的連接性，確保虛牆上的默認路由能夠指向實牆並順利轉發。

以上步驟應適用於大部分物理和虛擬防火牆的配置需求，具體命令取決於使用的防火牆品牌和型號。
