Ssh 和 Nat 转发

我是新来的，也需要处理网络问题。首先，如果我的帖子看起来乱糟糟的，我要道歉，因为我输入并复制了所有内容，在文本框中看起来不错，但预览却很乱。

我正在尝试使用 Raspberry Pi（带有 Ubuntu Server）作为备份服务器，因为我希望它无论身在何处都能工作，所以我决定使用 Dynu 来获取主机名，而不是一直依赖于检查我的公共 IP。然而，我很难让它工作。

当我在内部网络中时，我可以使用私有 IP 将所有机器相互连接（如预期的那样）。因此，下一步是配置我的路由器以将外部端口转发到机器中（我有一台装有 WSL Ubuntu 的 Windows 笔记本电脑，另一台装有 Solus Linux 的笔记本电脑，一台虚拟机和另一台 Pi，都装有 Ubuntu）。为简单起见，以下是地址：

Windows:             192.168.1.199 -> Port: 2199
Virt. Ubuntu:        192.168.1.103 -> Port: 2103
Rasp. Pi server:     192.168.1.111 -> Port: 2111
Rasp. Pi desktop:    192.168.1.105 -> Port: 2105
Solus:               192.168.1.109 -> Port: 2109

因此，如果我想连接到服务器，我需要输入 username@hostaddress -p 2111。而且它只在我离开网络时才有效（我使用手机作为热点）。但它不是应该独立于网络工作吗？

答案1

抱歉，我不得不暂时停止处理这个问题。结果如下：

Windows -> Raspeberry Pi 内部网络（已接受连接）

Windows -> Raspberry Pi 使用 DDNS（不起作用）

sudo tcpdump -n -tttt -vvv -i wlan0 port 22
tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 262144 bytes
^C
0 packets captured
0 packets received by filter
0 packets dropped by kernel

所以，肯定没有达到目的。我得拿出我的 Solus 笔记本，运行相同的命令，检查一下区别。谢谢

以下是我的 Solus 笔记本Windows -> Solus 使用内部网络的日志：
