  • 第4题：

    下面是防火墙接口的配置命令：

    fire(config) ip address outside 202.134.135.98 255.255.255.252

    fire(config) ip address inside 192.168.46.1 255.255.255.0

    fire(config) ip address dmz 10.0.0.1 255.255.255.0

    根据以上配置，写出上图中防火墙各个端口的IP地址：

    e0：(2)

    e1：(3)

    e2：(4)


    正确答案：(2)192.168.46.1 (3)202.134.135.98 (4)10.0.0.1
    (2)192.168.46.1 (3)202.134.135.98 (4)10.0.0.1 解析：本题考查的是。
    根据配置可知，该防火墙外网IP地址为202.134.135.98，内网IP地址为192.168.46.1， DMZ区的IP地址为10.0.0.1。
    从本题的示意图可知，防火墙e0口连接内部工作站，为内网接口；防火墙e1口连接Internet，为外网接口；防火墙e2口连接内部服务器，为DMZ接口。所以：
    e0：192.168.46.1
    e1：202.134.135.98
    e2：10.0.0.1
