  • 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
