udpspeeder、openvpn服务器安装在亚马逊EC2，udpspeeder 客户端安装在vmware虚拟机上，网络桥接到win10，openvpn 客户端安装在win10上面。

udpspeeder server: ./speederv2_amd64 -s -l0.0.0.0:4096 -r127.0.0.1:1194 -k "passwd" -f2:4 --timeout 1
udpspeeder client：./speederv2_x86 -c -l0.0.0.0:3333 -r18.183..*:4096 -k "passwd" -f2:4 --timeout 1

UDPSpeeder 服务器和客户端看起来是连接成功的，运行情况如下：

openvpn客户端提示连接超时，日志提示:Server poll timeout, trying next remote entry...

在服务器端已执行网络设置如下：
echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 10.222.0.0/16 ! -d 10.222.0.0/16 -j MASQUERADE

我自己判断是udpspeeder服务器收到数据后没能成功把数据转发给openvpn服务器，请教一下该如何才能连上VPN，非常感谢各位大神。
