1.我在Vmvare中安装了centos7，并且在centos7中安装了tomcat并在防火墙中开放了访问端口，windows中用浏览器可以正常访问看到黄猫的界面，centos7内部自带的火狐浏览器不能访问，显示链接被重置。求助，可能的原因是什么啊？
2、同时我在centos7中部署了nginx反向代理tomcat集群，部署了两台tomcat，并且能够分别正常访问。我在nginx.conf中添加了代理配置，但是通过nginx服务器访问我的项目显示404，查看日志显示请求的路径是nginx安装目录下的html/test，test是我的项目，这是不是说明我的nginx服务器根本没有去tomcat中请求服务，我的请求到nginx中就终止了，他直接到自己的html目录下面查找我的项目，因为没有我的项目，所以报错，为什么会这样啊？（能确保nginx服务器安装无误，gcc等依赖编译包都正确安装，nginx.conf中的配置也确保正确，求助，还会有什么原因导致这种情况）
（以上两个问题都是在公司内网环境下，通过代理上网的）
这两个问题困扰我好几天了，希望能够得到广大猿友们帮助QAQ
