Ubuntu 服务器 (apache) 不会响应外部请求

Question

我对此很陌生，所以我可能会遗漏一些非常明显的东西，但我无法使用我的外部 IP 连接到我的服务器。在内部，一切都像梦一样工作（10.0.0.28/redmine），但是当我尝试使用外部 IP 连接时，请求超时。我转发了我的 ssh 端口和端口 80，如下所示，但这并没有解决问题。 我的端口现在显示为通过 www.portchecktool.com 打开。

SSH 在内部工作正常，但是当我发出此处显示的命令时，它显示连接已被远程主机关闭。

ssh {my external ip} -pxxxx -i /home/millerir/.ssh/id_rsa -l imiller

同样，当我导航到 {my ip}/redmine 或 {my ip} 或 {my_ip}:80 或我的 ddns 服务地址时，我在尝试从浏览器连接错误时重置连接。

我确实检查了服务器正在侦听端口 80 和我的 ssh 端口，如下所示。

me@ubuntu-server:/etc/apache2/sites-available$ sudo netstat -tulpn | grep LISTEN
tcp        0      0 0.0.0.0:xxxx            0.0.0.0:*               LISTEN      779/sshd
tcp        0      0 127.0.0.1:57384         0.0.0.0:*               LISTEN      1192/redmine
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      862/mysqld
tcp6       0      0 :::xxxx                 :::*                    LISTEN      779/sshd
tcp6       0      0 :::80                   :::*                    LISTEN      923/apache2

如果有人可以帮助我，将不胜感激。我被卡住了，有点不知所措。

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the

        # after it has been globally disabled with "a2disconf".

所以我在四处挖掘后发现有些路由器不喜欢你“进出”。我尝试使用手机上的数据连接到我的服务器，现在它可以正常工作了。
