用于隧穿分组的ISATAP路由器及其方法
摘要：
提供了一种用于隧穿分组的站内自动隧道寻址协议(ISATAP)路由器及其方法。ISATAP主机的私有IP地址和公共IPv4地址信息存储在映射表中，使用IPv6分组和映射表对从IPv6主机接收的IPv6分组将要发送到的网络地址转换器(NAT)的公共IPv4地址进行检查，将IPv6分组封装在IPv4报头内并隧穿到网络地址转换器(NAT)，其中IPv4报头的目的地址是网络地址转换器(NAT)的公共IPv4地址。因此，不需要改变网络地址转换器(NAT)就能够将ISATAP主机与IPv6网络相连。
摘要（英）：

An Intra-Site Automatic Tunnel Address Protocol (ISATAP) router for tunneling packets and a method thereof are provided. A private IP address of an ISATAP host and public IPv4 address information are stored in a mapping table, a public IPv4 address of a Network Address Translator (NAT), to which an IPv6 packet received from the IPv6 host is to be transmitted, is checked using the IPv6 packet and the mapping table, and the IPv6 packet is encapsulated within an IPv4 header whose destination address is the public IPv4 address of the Network Address Translator (NAT), and tunneled to the Network Address Translator (NAT). Thus, the ISATAP host and the IPv6 network can be connected without changing the Network Address Translator (NAT).
