华为usg6300防火墙，通过命令如何配置上网，懂命令的人，对于防火墙出现故障会更好判断问题，防火墙基本的上网命令如何去配置？

华为防火墙命令配置过程

1.虽说我们使用命令去调试华为的防火墙，但是我们还是需要将web界面打开的，使用web-manager enable，开启防火墙的web界面。

2.查看一下防火墙的现有配置，可以看到当前的G0/0/0号口IP地址是默认的192.168.0.1/24，而且默认开启了http和https登录，允许被ping。

3.在配置命令时，关闭log响应，这样配置起来会更顺畅。使用undo info-center enable，关闭log日志。

4.划分防火墙的接口区域，因为防火墙是接口分区域的，在之前的文章中已详细讲解防火墙的接口区域划分，请兴趣的可以参考：小白也能看的懂，网络防火墙的入门篇

将G0/0/1划分到外网连接接口，Untrsut。

使用zone untrust进入到untrust区域，然后使用add添加接口到untrust区域。

添加完成之后，查看配置，可以看到优先级，默认的配置就是5，可以看到Untrust区域，已经添加了一个接口是G0/0/1。

将G0/0/3和G0/0/4添加到Trust区域。

使用zone trust进入到trust区域，然后还是使用add添加接口到信任区域。

添加完成之后，查看Trust区域配置，可以看到默认的trust区域的优先级是85，里面有一个G0/0/0是默认添加到Trust区域的，还有两个接口是手动添加进来的。

5.DHCP配置

为3网段启用DHCP功能，对于想详细了解DHCP如何配置的，请参考：什么你还不会用命令行，去配置华为防火墙的DHCP服务？

ip pool dhcp1

gateway-list 192.168.10.1 192.168.3.1

network 192.168.3.0 mask 255.255.255.0

excluded-ip-address 192.168.3.200 192.168.3.254

lease unlimited

dns-list 114.114.114.114

6.配置接口IP地址，公司现在要有两个网段，一个是192.168.3.0/24网段，一个是192.168.4.0/24网段。

外网口配置，untrust区域，接口配置：

interface GigabitEthernet0/0/1

undo shutdown

ip address 192.168.10.200 255.255.255.0

内网口：trust区域，物理接口配置：

由于是内网口，为了维护方便，直接将所有管理服务允许。

service-manage all permit--允许所有协议登录

配置G0/0/3 IP地址。

interface GigabitEthernet0/0/3

undo shutdown

ip address 192.168.3.1 255.255.255.0

service-manage http permit

service-manage https permit

service-manage ping permit

service-manage ssh permit

service-manage snmp permit

service-manage telnet permit

service-manage netconf permit

dhcp select global--使用的全局DHCP功能。

G0/0/4接口启用的是接口DHCP服务。

interface GigabitEthernet0/0/4

undo shutdown

ip address 192.168.4.1 255.255.255.0

dhcp select interface

dhcp server excluded-ip-address 192.168.4.2 192.168.4.20

dhcp server dns-list 218.2.135.1

7.配置NAT策略

使用Nat-Policy命令，进入到NAT策略配置中。因为我们这里，只有一个外网口，而且是默认将内网口转发出即可，可以配置easy-IP最简单。将所有流量，都转发到外网口，Untrust接口IP地址。

[USG6300-FW]nat-policy

[USG6300-FW-policy-nat]rule name trust-untrust---定义一下Nat策略的规则

[USG6300-FW-policy-nat-rule-trust-untrust]egress-interface GigabitEthernet 0/0/1-----定义外网口是G0/0/1接口，英[ˈiːɡres]出口、外出

[USG6300-FW-policy-nat-rule-trust-untrust]action nat easy-ip---将内网用户的源地址转换为外网接口的地址

[USG6300-FW-policy-nat-rule-trust-untrust]dis thi--配置完成之后，查看nat配置

2023-11-07 22:47:10.440+08:00

#

rule name trust-untrust

egress-interface GigabitEthernet0/0/1

action nat easy-ip

#

return

8.安全区域放行，在防火墙，一共有四个接口区域，untrust、trust、dmz、local，不同区域之前通信，都需要在在防火墙上设置安全策略，允许或禁止不同区域之间的流量访问。

[USG6300-FW]security-policy---进入安全策略

[USG6300-FW-policy-security]rule name trust-untrust---规则名称是trust流量去往untrst

[USG6300-FW-policy-security-rule-trust-untrust]source-zone trust---源区域是trust

[USG6300-FW-policy-security-rule-trust-untrust]destination-zone untrust---目的区域是untrust

[USG6300-FW-policy-security-rule-trust-untrust]source-address any--源地地址是任何IP地址

[USG6300-FW-policy-security-rule-trust-untrust]destination-zone any---目的区域，也是任何地址。

[USG6300-FW-policy-security-rule-trust-untrust]service any---访问的服务也是任何服务

[USG6300-FW-policy-security-rule-trust-untrust]action permit---动作是允许访问

[USG6300-FW-policy-security-rule-trust-untrust]quit---退出

[USG6300-FW-policy-security]dis thi---查看配置

2023-11-07 22:37:23.830+08:00

#

security-policy

rule name trust-untrust

source-zone trust

action permit

#

9.配置默认路由

ip route-static 0.0.0.0 0.0.0.0 192.168.10.1

此命令用于配置默认路由，将所有未知目的地的流量发送到指定的网关地址（192.168.10.1）。

10.这时如你电脑连接到G0/0/3口，会自动获取一个IP地址，可以正常上网。

11、配置导出。
