SecBlade 防火墙单板透明模式保护多VLAN的配置

SecBlade 防火墙单板透明模式保护多VLAN的配置

 

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，内网有两个VLAN需要保护（VLAN30、VLAN40）。

二、  组网图：

软件版本如下：

S8505: VRP310-E1326

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/VLAN40三层不可终结在S8500上，否则VLAN30/VLAN40和VLAN50通过三层直接可达，数据将不通过SecBlade;通过将VLAN30/VLAN40设置为security-vlan将trust区域的数据送给SecBlade。

2、                S8500内部接口作为vlan30/vlan40的网关，由于secblade-interface Vlan-interface 只能有一个，因此，通过设置sub地址的方法。      

                         interface Vlan-interface60                     //与SecBlade内部接口                                      

                         ip address 30.0.0.254 255.255.255.0    //vlan30用户的网关                               

                     ip address 40.0.0.254 255.255.255.0 sub    //vlan40用户的网关         

3、                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

4、                注意防火墙板内部子接口加入安全区域。
