我正在按照以下说明连接到 VPN 服务器 https://github.com/hwdsl2/setup-ipsec-vpn
我设置了以下客户端https://github.com/hwdsl2/setup-ipsec-vpn/blob/master/docs/clients.md#os-x
在同一个局域网下，我的一个客户端（OSX 10.14.5，防火墙关闭）连接成功

有人可以给我提示吗？
答案1
导航到/etc/ppp。
如果有任何文件，例如options，请检查它。
可能有：
/etc/ppp % cat options
plugin L2TP.ppp
l2tpnoipsec
所以你应该删除该options文件然后你就会得到积极的结果。
