OSX10.6思科IPSEC的奇怪行为

Question

我正试图通过DSL互联网连接到我公司的思科IPSEC VPN。我成功地使用Cisco VPN客户端进行了连接，现在由于许可证问题，我试图切换到OSX10.6本地客户端。

问题是，包含以下消息的对话框会导致连接失败：

The negotiation with the VPN server failed. Verify the server address and try reconnecting.

我查过日志：

然后我打开了终端，开始在VPN后面点击一个服务器，然后尝试再次连接。现在连接没问题！这次日志：

我对它进行了几次测试，结果始终是一样的。魔法是什么？

在OSX10.7中没有注意到这个问题，因此任何人都会坚持这个问题--只需更新到Lion :)
