问题描述：

社区的大神们，小弟我这几天碰到一个很奇怪的问题，本人是某市一局办单位的网管，本单位需要通过VPN和本市的国土局连接，办理相关业务。

关于VPN的具体配置为：vpn服务服务器在国土局，使用的是网神的防火墙的VPN功能，VPN的类型是SSLVPN，本单位如要使用VPN功能，先通过HTTPS的方式登录在国土局的防火墙的外网地址：https://172.23.XX.XX:64443,下载一个SSLVPN客户端（必须要下载）并安装好，同时电脑上会有一个虚拟网卡，双击安装好的客户端，输入用户名和密码，就连上VPN了，通是虚拟网卡也分配到了IP地址，到这里都是正常的。

然后问题来了，既然连上VPN了，就开始访问位于国土局的内网地址（OA）以及打开位于本单位电脑上的档案查询软件（软件服务器在国土局的内网上），但是访问速度非常慢，打开OA网址要十几分钟，软件更是打不开，一开始还以为是国土局那边的VPN没配好，打电话过去问，得知其他的局办单位都是正常了，没有出现说是速度慢的情况，然后怀疑是账号权限问题，但是让其他局办单位的小兄弟用我的账号登录他那边的VPN，一切正常，访问OA和软件一切正常，速度很快。在然后我们试了一下另一种情况，就是插路由器WAN口的网线直接插电脑了，电脑网卡配路由器外网接口（这样电脑网卡上实际上配的是公网地址），然后奇迹出现了，VPN访问很正常了，有点也不卡了。到这里，可能会有大神就会说，那可能是我们内部网络有问题了，但是我们单位的外网上网很正常，访问外网网页速度也很好。就是连上VPN后，访问不了国土局的内部资源。其他局办单位都正常，就我们单位不正常。另外关于VPN在客户端的配置，其他访问正常的局办单位，也和我们一样，先用网址登陆VPN服务器（实际是网神防火墙的外网接口地址），然后跳出一个下载SSL客户端的网页，下载客户端，按提示安装好，打开客户端，输入账号密码，连上VPN，其他也不用配的。

本单位的核心交换机用的是S7500系列核心交换机，核心交换机上插着一块防火墙板卡，路由器是H3CSR6604，访问外网做NAT转换

社区上大神们，能不能帮我分析一下，是哪里出的问题，谢谢了

你比较下各接口的MTU和tcp mss 参数是否一致，

那你可以这样试试，电脑直接接路由器试试，如果可以，然后再接交换机上试试看
