我试图通过DSL互联网连接到我公司的思科IPSEC VPN。 我设法成功连接使用思科VPN客户端，现在我试图切换到OSX 10.6本地客户端，由于许可问题。
问题是连接失败，并显示一个包含消息的对话框：
The negotiation with the VPN server failed. Verify the server address and try reconnecting. 我检查了日志：

然后，我打开terminal，开始ping VPN后面的服务器 ，并尝试再次连接。 现在连接就OK了！ logging这次：

我testing了几次，它一贯的行为是一样的。 什么是魔法？
这个问题在OSX 10.7中没有被观察到，所以任何人都坚持这一点 – 只是更新到狮子:)
