為了外網能訪問內網svn。於是坐在外網端口映射。但是奇怪的是內網能訪問，外網總也登錄不進去。以為是瀏覽器版本低
但是其他瀏覽器也一樣。最后客戶端也登錄不進去。提示報錯：

credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.
網上搜索解決方案無果，懷疑外網防火牆或映射時做了安全過濾。但是tcp和utp都已經設置了。
最終發現...端口竟然被公司內網其他端口給占用了。原來外網端口可以映射內網多個端口竟然不剖異常...
最后新開端口並做了映射...問題也迎刃而解了....
