查看“Firewall-cmd配置端口转发”的源代码


=firewall-cmd配置端口转发=

==firewall status==
systemctl status firewalld.service

==重新加载防火墙==
firewall-cmd –reload

==Rule List==
firewall-cmd –list-all

==设置==

===检查是否允许伪装IP===
firewall-cmd –query-masquerade

*firewall-cmd –add-masquerade –permanent
*–add-masquerade  # 允许防火墙伪装IP
*–remove-masquerade# 禁止防火墙伪装IP

===永久生效===

*–permanent 永久生效，否则重启/reload失效

===开放端口===

*firewall-cmd –zone=public –add-port=32000-32099/tcp
*firewall-cmd –zone=public –add-port=33000-33099/udp
*firewall-cmd –zone=public –remove-port=32000-32099/tcp

===转发===

*firewall-cmd –add-forward-port=port=32010:proto=tcp:toport=3389:toaddr=193.122.104.2
*firewall-cmd –remove-forward-port=port=32010:proto=tcp:toport=3389:toaddr=193.122.104.2

=== 批量添加端口映射 ===
