我之前已经看过几次这样的问题,但到目前为止,他们都没有解决我的问题.
我正在尝试在我的Ubuntu服务器上设置一个IKEv2 VPN,以便与使用Strongswan的Windows Phone一起使用.连接似乎设置正确,但没有路由数据包,我无法ping VPN客户端的IP地址.
我的服务器的内部网络是192.168.1.0/24,我的服务器的IP是192.168.1.110并且在NAT之后.

有些事情对我来说有点奇怪(当连接建立时,不应该提起ipsec0或某事吗？),但是我很难过这一点,并且非常感谢一些帮助.
编辑：注释掉protoport行并取消了tun0接口.
你需要：
$iptables -t nat -A POSTROUTING -o eth0 ! -p esp -j SNAT –to-source “your VPN host IP”
