SecBlade防火墙单板NATServer的配置

SecBlade 防火墙单板NATServer的配置

一、  组网需求：

SecBlade防火墙单板作为NAT网关对内网网段做NAT并对内部服务器做NATServer，内网的网关终结在S8500上。

二、  组网图：

要做NAT网关，SecBlade板只能工作在路由模式，S8505创建三层接口int Vlan-interface 40，作为与SecBlade的内部接口，内网PCA的网关在S8500上，防火墙板作nat和natserver，使trust区域的用户能访问公网 。

软件版本如下：

S8505: VRP310-R1271

SecBlade：VRP3.4-ESS1209

三、  配置步骤：

本配置适用于S8500VRP3.1-R1271及以后版本，SecBlade VRP3.4-E1209及以后版本。

四、     配置关键点：  

1、SecBlade上要有到内网和外网的路由；S8500上要有到外网的路由，下一跳指向SecBlade。

2、注意将SecBlade子接口加入安全域。
