防火墙策略

首先规划和配置IP地址

在防火墙开启DHCP服务,创建地址池,并关联到防火墙的内部端口

  [SRG]dhcp server ip-pool 188
  [SRG-dhcp-188]network 192.168.1.0 mask 24
  [SRG-dhcp-188]gateway-list 192.168.1.1
  [SRG-dhcp-188]qu

  然后在pc1上ipconfig,已经可以自动获得IP地址

  

 在AR1上配置telnet服务器

  [Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.1.1
  [Huawei]user-interface vty 0 4
  [Huawei-ui-vty0-4]authentication-mode password 
  Please configure the login password (maximum length 16):tel123
  [Huawei-ui-vty0-4]qu

 AR3配置

  [Huawei]ip route-static 0.0.0.0 0.0.0.0 202.101.10.1

 AR4配置

  [Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.2.1

 AR2配置

  [Huawei]rip
  [Huawei-rip-1]version 2
  [Huawei-rip-1]network 202.101.12.0
  [Huawei-rip-1]network 202.101.10.0
  [Huawei-rip-1]network 202.101.15.0

 防火墙配置

[SRG]firewall packet-filter default permit interzone trust untrust direction out bound   ##开启trust到untrust的默认行为为允许
Warning:Setting the default packet filtering to permit poses security risks. You
are advised to configure the security policy based on the actual data flows. Ar

杂念太多,必然根基浅薄
