nat-t
This document describes details on how NAT-T works. Background: ESP encrypts all critical information, encapsulating the entire inner TCP/UDP datagram within an ESP header. ESP is an IP protocol in the same sense that TCP and UDP are IP protocols (OSI Ne, Traditionally, IPSec does not work when traversing across a device doing NAT/PAT(Network Address Translation and Port Address Translation), meaning if either one of the devices or both the devices terminating IPSEC is behind a NAT device, IPSEC will not

IPsec VPN客戶普遍使用NAT-T來達到使ESP包通過NAT的目的。 儘管有許多穿越NAT的技術，但沒有一項是完美的，這是因為NAT的行為是非標準化的。這些技術中的大多數都要求有一個公共伺服器，而且這個伺服器使用的是一個眾所周知的、從全球任何地方都能訪問得到的IP位址。一些方法僅在建立連接時需要使用這個伺服器，而 ... https://zh.wikipedia.org NAT穿透技術從外部直接溝通私有IP - 技術專欄- 網管人NetAdmin
