命令详解

--add-rich-rule #添加访问规则
----------------------------------------------------------------------------
man firewalld.richlanguage #查看rich 语法详细说明
----------------------------------------------------------------------------
Example 5
 Forward IPv6 port/packets receiving from 1:2:3:4:6:: on port 4011 with protocol tcp to 1::2:3:4:7 on port 4012
    rule family="ipv6" source address="1:2:3:4:6::" forward-port to-addr="1::2:3:4:7" to-port="4012" protocol="tcp" port="4011"
----------------------------------------------------------------------------
rule family="ipv4" source address="192.168.142.166" port port="10-20" protocol="tcp" accept   

常用命令

firewall-cmd --reload

--permanent代表永久开启/关闭 端口,不加代表临时,每次添加了永久的之后运行上面的reload命令 ,用了上面的reload命令临时添加的会失效

firewall-cmd --list-all
firewall-cmd --permanent --zone=public --add-port=81/tcp
firewall-cmd --permanent --zone=public --add-port=8080-8083/tcp
firewall-cmd --permanent --zone=public --remove-port=81/tcp
firewall-cmd --list-all-zones 
iptables -A INPUT -s 10.100.103.15  -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -s 10.104.101.0/22  -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP
iptables -A INPUT -s 10.100.103.12 -p udp --dport 123 -j ACCEPT
iptables -A INPUT -p udp --dport 123 -j DROP
-----------------------------------------------------------------------------------------------------
firewall-cmd --add-rich-rule="rule family="ipv4" source address="10.100.103.12/32" port protocol="udp" port="123" accept" --permanent
firewall-cmd --add-rich-rule="rule family="ipv4" source address="10.104.101.0/22" port protocol="tcp" port="22" accept" --permanent
firewall-cmd --add-rich-rule="rule family="ipv4" source address="10.100.103.15/32" port protocol="tcp" port="22" accept" --permanent
