In tunnel mode, the inner IP header carries the intended source and original destination addresses, while an outer IP header contains IP addresses for hop points such as security gateways.

在隧道模式，内部的ip报头承载预设的源和最初的目的地址，外部ip报头包含用于跳点的IP地址，比如安全网关。

The ESP header is located after the IP header and before the transport mode protocol (UDP or TCP) or before an encapsulated IP header when using tunneling.

ESP报头位于IP报头之后，传输模式(UDP或者TCP)之前，或者当使用隧道时是在封装的IP报头之前。
