無法從遠端電腦透過 ssh 連接，但可以在本機連接

我有一台運行 openssh 的 archlinux 計算機，我可以毫無問題地在本地連接到它。但是，當我嘗試從另一個網路連接時，我收到錯誤。 SSH 正在偵聽連接埠 22，但我將路由器設定為將連接埠 25 連接埠轉送到 22，因為我有不只一台電腦設定為透過 ssh 進入連接埠 22。

使用膩子，I get Incoming packet was garbled on decryption我嘗試將河豚移到頂部，並在“連接”>“SSH”>“密碼”中嘗試將 3DES 移到頂部。我使用的是膩子版本.64

使用 MobaXterm 我得到

Bad packet length 1349676916. Disconnecting: Packet corrupt 當我手動運行時

ssh username@ip -vp 25

如果我在運行 ssh 時使用 -1 我得到

Protocol major versions differ: 1 vs. 2

據我了解，連接埠已正確轉送。我還用 telnet 連接並得到了

Trying MY-IP...
Connected to MY-IP.
Escape character is '^]'.
SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u2

我可以連接到網路上的其他機器，然後使用它們透過 ssh 連接到這台機器。另外兩台機器是樹莓派，我覺得嘗試使用它們作為接入點可能會導致延遲，所以如果可能的話我寧願修復這個問題。

答案1

似乎正在使用連接埠 35。切換到另一個連接埠並將其設定為靜態IP似乎已經解決了問題。
