Implementation of traversing firewalls and NATs in H.323 based on tunnel mechanism

基于隧道机制实现H.323中防火墙和NAT的穿越

Compared to UDP , establishing TCP connections for hosts behind different NATs is more complex .

相比UDP，在位于不同NAT后的多台主机间建立TCP连接要复杂很多。

Improvement on Tunnel IPv6 over UDP Through NATs

对UDP中穿越NATs的IPv6隧道的改进

However , not all NATs in the wild react the same way , causing these approaches to fail in various cases .

然而在外网上，不是所有的NAT都能这么做，还是有很多种的情况会导致这些步骤的失败。

Until now , several groups have focused on this field and their results suggest that NATs are much more than we have expected before .

迄今为止，已有多个研究小组作了相关探索，他们的研究结果表明NATs比我们想象的要多得多。

The outbound SYN packet from each host creates the necessary NAT state for its own NATs .

从各自的主机外出的SYN包，为他们自己的NAT产生可能的NAT状态。

Even so , NATs and firewalls have become a permanent part of the network infrastructure and will continue to remain so for a long time .

尽管如此，NAT和防火墙在网络下层构架中还是一个永远不可替代的部份，而且会在很长的时间内继续扮演下去。

CONCLUSION Solanine is a non-competitive inhibitor of NATs .

结论龙葵碱是NAT酶2-AF底物的非竞争性抑制剂。

It does a research on IP , IPSec protocol and propose a new multilayer encapsulation method of tunnel technology for private address behind different NATs based on p2p .

研究了IP，IPSec协议，采用了一种新的多层封装隧道技术实现不同NAT后主机的IPSec通信及其具体工作过程。

Finally , our results can be used to guide the standardization process of NATs and firewalls , making them more traversal friendly without circumventing security policies .

最后，我们的结果能被用于引导标准化的NAT和防火墙程序的开发，使得它们不需要围绕严格的策略就能更加友好地穿越。

Understanding such behavior in NATs and measuring how much they detract from the original goal of universal connectivity in the Internet is crucial to integrating them cleanly into the architecture .

明白了NAT的行为，确认有多少在网络上的原始目的地连接，能很是清楚地把他们结合进框架中来。

Even if IPv6 is deployed globally , IPv4-IPv6 NATs will be needed during the lengthy transition , and IPv6 firewalls will be needed for security .

甚至当IPv6的展开全球化，在过度的转换中还是需求IPv4-IPv6NAT来进行地址转换，而且IPv6防火墙将会被用于安全方面。

This paper studies the security techniques for voice and video over IP to traverse NATs / Firewalls , and proposes an effective and transparent scheme to pass through NATs / firewalls .

本文研究IP音视频安全穿越NAT／防火墙的技术，提出了一种安全穿越NAT／防火墙的有效透明穿越方案。

But British airspace remained largely closed to flights below 6,000 metres owing to ongoing fears about the danger posed by volcanic ash , Nats , the air traffic control body said .

但英国航空管制机构NATS表示，出于对火山灰威胁的担心，英国6000米以下空域仍基本禁飞。

UDP Hole Punching enables two peers to set up a direct P2P UDP session with the help of a well-known rendezvous server , even if the peers are both behind different NATs .

采用了“UDP打洞技术”之后，在服务器的帮助下，处于不同局域网的用户之间也可以P2P通信。

Glutathione S-transferases ( GSTs ) and N-acetyltransferases ( NATs ) are deeply related to the metabolism , activation and detoxification of xenobiotics .

谷胱甘肽硫转移酶（GSTs）和N-乙酰转移酶（NATs）与异源物质（xenobiotics）在人类的代谢、激活、解毒等过程密切相关。

This solution implements NATs traversal by modifying the SIP messages the proxy relays and redirecting the media flow of the terminals to the proxy . It 's a simple , efficient solution that complies with SIP protocol .

该方案通过修改中转的SIP消息的媒体信息，使终端将媒体信息发送到Proxy处转发，从而实现了防火墙穿透。
