centos - win下连接openvpn失败

Question

win下可以不安装openvpn客户端直接通过网上邻居新建vpn通道来连接吗？
1.我的server端是同网段的一个虚拟机 用的桥接连接到交换机的
2.server端的环境是centos 6.4的
3.我配置环境的log指明在/var/log/openvpn.log(该log中只有服务成功的log 没有errorlog)
4./etc/openvpn/目录下有一个状态log没有看到任何连接请求log
5.service openvpn restart 关闭 开启服务都是正常反馈 都是OK

------------------------

下面是server.conf 配置信息

----------------------------

• cal 125.125.126.12 #11.22.33.44为VPS的IP

2 port 1194 #端口，需要与客户端配置保持一致，并保证与其他软件无共用
3 proto udp #使用协议，需要与客户端配置保持一致
4 dev tap
5 mode server
6 #dev tun #也可以选择tap模式
7 ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt
8 cert /etc/openvpn/easy-rsa/2.0/keys/server.crt

-------------------------------------------------------------------------

我认为可能连接未被发起请求进来(因为server端没有log)
客户端是win 2003的环境 通过网上邻居新建vpn通道进行连接的
返回的是800错误 连接失败 还未涉及到证书问题 因为没有连接log

Q：1.是否是因为openvpn的客户端连接必须安装openvpn客户端 否则是无法连接的 没道理啊 按道理至少应该是有请求的
2.我在server端netstat -nl (没有server.conf里面的监听端口) 那是不是我的服务端也存在问题
请高手指点

------------------下面是netstat -nl的信息--------------------------

Answer 1

不可以，必须安装 OpenVPN 客户端
