默认target是指当匹配到某个规则时,Firewalld默认采取的策略。非默认target则是在默认target基础上,针对特定场景或需求进行的扩展。 接下来,我们详细解析default target。默认target包含以下几种策略: 1.拒绝(Reject):当匹配到拒绝规则时,Firewalld会拒绝相应的连接或数据包。 2.放行(Accept):当匹配到放行规则时,...
预先定义的 zone 规则被放在/usr/lib/firewalld/zones/目录下。当修改 zone 的规则时,这些 zone 会被拷贝到/etc/firewalld/zones/目录下,实际生效的防火墙会在该目录下的文件。 对于每一个 zone 都有一个默认的行为(target),来处理流入的流量。每个 target 会有四个选项:default,ACCEPT,REJECT和DROP. ACCEPT...
