配置Nat策略

配置策略,使得trust区域可以访问untrust区域

配置默认路由,指向R1

设置到达Nat Pool的静态路由,指向一个空接口,防止路由黑洞

配置防火墙使得外网用户能访问企业DMZ区域的FTP服务器(双向nat)
先配置服务器对外静态映射

防火墙上配置一个策略,使得untrust区域能访问DMZ区域

配置nat pool地址池,目的是作为外网用户访问内网服务器后nat的内网地址

配置一个nat策略。注意,这个nat策略和内网nat外网有所不同!!!

最后配置一个到达服务器对外地址的静态路由,防止路由黑洞

自我介绍一下,小编13年上海交大毕业,曾经在小公司待过,也去过华为、OPPO等大厂,18年进入阿里一直到现在。
深知大多数初中级Android工程师,想要提升技能,往往是自己摸索成长,自己不成体系的自学效果低效漫长且无助。
因此收集整理了一份《2024年Web前端开发全套学习资料》,初衷也很简单,就是希望能够帮助到想自学提升又不知道该从何学起的朋友,同时减轻大家的负担。



既有适合小白学习的零基础资料,也有适合3年以上经验的小伙伴深入学习提升的进阶课程,基本涵盖了95%以上Android开发知识点!不论你是刚入门Android开发的新手,还是希望在技术上不断提升的资深开发者,这些资料都将为你打开新的学习之门!
如果你觉得这些内容对你有帮助,需要这份全套学习资料的朋友可以戳我获取!!
由于文件比较大,这里只是将部分目录截图出来,每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频,并且会持续更新!
