SSH隧道“通道x:打开失败:连接失败:连接超时”

Question

我在谷歌上搜索了很多地方，寻找解决这个问题的方法；然而，我得到的最好的答案是“什么都做不了。”当然，这是令人不满意的，所以这里说：

我已经在家里设置了一个SSH守护进程，我想要将它导入SSH隧道。SSH的工作没有问题。隧道似乎也没有问题。本地执行的命令是..。

~$ ssh root@xxx.yyy.zzz.aaa -p 53256 -D11323

家里的东西有一个路由器，它将端口53256端口转发到我的ssh服务器，端口22。一切都连接得很好，隧道表面上也很正常。在机器上，我为127.0.0.1:11323放置了一个SOCKS代理，我可以很好地访问站点。然而，当访问特定的网站，如ubuntuforums.org或fedoraforums.org，连接挂起相当多。然后，带有ssh命令的shell将显示标题中的错误，而连接就会失败。阅读之后，我得到的最接近的答案是，“服务器负载或配置不当”存在问题。然而，让我感到困惑的是，我绝对无法通过隧道连接到这些网站。尽管如此，有谁能提供一个解决方案呢？

编辑:这是在失败之前启用SSH的-vv选项的输出：

我是个笨蛋。我在服务器上设置了一些古怪的iptable规则。清除了所有这些之后，一切都很好。抱歉打扰你了。
