In this activity, you configure a basic ZPF on an edge router R3 that allows internal hosts access to external resources and blocks external hosts from accessing internal resources. You then verify firewall functionality from internal and external hosts.The routers have been pre-configured with the following: Console password: ciscoconpa55 Password for vty lines: ciscovtypa55 Enable password: ciscoenpa55 Host names and IP addressing Static routing介绍:ZPF 防火墙是思科公司近期研发的技术之一,在这个任务中,我们在边界路由器 R3 中配置策略,运行内部主机可以访问外部资源,相反的,不允许外界主机访问内网的资源。路由器中已经配置好的参数如下: 控制台密码: ciscoconpa55 Password for vty lines: ciscovtypa55 Enable password: ciscoenpa55主机的名字和 IP 地址静态路由。Task 1: Verify Basic Network ConnectivityVerify network connectivity prior to configuring the zone-based policy firewall.Step 1. From the PC-A command prompt, ping PC-C at 192.168.3.3.Step 2. From the PC-C command prompt, Telnet to the Router R2 S0/0/1 interface at 10.2.2.2. Exit the Telnet session.Step 3. From PC-C, open a web browser to the PC-A server.Click the Desktop tab and click the Web Browser applicatio
