防火墙安全策略
实验图
1.配置防火墙图形界面
先添加UDP端口
添加网段网卡
注意：
网段网卡Windows上，所以Windows可以通过这个网段网卡访问到防火墙上
做端口映射，点击双向通道，点击添加
注意：
一般情况下防火墙在刚买下会有一个端口为管理口，自带IP地址，华为设备中，防火墙默认只有GigabitEthernet0/0/0端口是受信任端口，且ip地址为192.168.0.1
启动防火墙FW1
启动成功后，会提示输入Username以及Password
华为默认用户名以及密码为：
Username：admin
Password：Admin@123
登录成功后提示修改密码The password needs to be changed. Change now? [Y/N]: yPlease enter old password: Please enter new password: Please confirm new password: Info: Your password has been changed. Save the change to survive a reboot. ************************************************************************** Copyright (C) 2014-2018 Huawei Technologies Co., Ltd. ** All rights reserved. ** Without the owner's prior written consent, ** no decompiling or reverse-engineering shall be allowed. **************************************************************************Mar 17 2023 08:22:41 USG6000V1 SNMPADAPT/4/UPDATE_SUCCESS:OID 1.3.6.1.4.1.2011.6.122.76.2.1 Succeed in updating database.

输入图形化界面的访问地址
登陆刚才设置的用户名以及密码
2.配置untrust区域
点击网络，进入接口
配置GE1/0/0接口
注意：
写上网关会出现默认路由，一般情况不写，自己进行配置
R1配置
