指定特定源IP访问某端口

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.100.1" port protocol="tcp" port="80" accept"   #添加源IP 192.168.100.1访问80端口
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.100.0/24" port protocol="tcp" port="80" accept"  #添加IP段访问80端口
firewall-cmd --permanent --remove-rich-rule="rule family="ipv4" source address="192.168.100.1" port protocol="tcp" port="80" accept"   #删除源IP 192.168.100.1访问80端口

批量添加区间端口
