我有问题连接SSH到远程主机,但只在我的家庭网络(提供商).如果我在另一个网络(我在同一个城市的朋友 – 不同的提供商),连接工作完美. Ping到服务器(在我家)工作.这个问题我只有这个服务器.如果我尝试从家庭网络连接到其他主机,它可以工作.我该怎么办？

解决方法
以下是您可以尝试创建隧道的方法.
>中介是您信任的为您转发的机器
> remote是你想要的机器
ssh -N -L 20000:remote:22 user@intermediary
执行此操作后,本地计算机将侦听端口20000.当您使用ssh连接到此端口时,在您的主机上,连接将通过隧道转发给中间人,后者又将其转发到远程端口.
