SecBlade 防火墙单板透明模式的配置（二）

SecBlade 防火墙单板透明模式的配置（二）

 

一、  组网需求：

SecBlade防火墙单板工作在透明模式，内网和外网的网关终结在S8500上。

二、  组网图：

一般情况下，S8500工作在三层模式下，比如：S8500上配置两个interface vlan 30 /50分别作为内网和外网的vlan终结：

 

如果要在不改变现有网络情况下，增加SecBlade： 

 

TRUST区域的通过S8500二层vlan30（security-vlan）转发到SecBlade，从SecBlade出来，打上vlan60的标签，终结在S8500的三层interface vlan60上，然后三层vlan50转发出去。

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、                VLAN30三层不可终结在S8500上，否则VLAN30和VLAN50通过三层直接可达，数据将不通过SecBlade;通过将VLAN30设置为security-vlan将trust区域的数据送给SecBlade。

2、                防火墙透明模式下将未知mac报文的处理方式设置为flood。

       firewall unknown-mac flood

3、                注意防火墙板内部子接口加入加入安全区域。
