Network security protocol IPSec (IP Security) and TLP181 datasheet and Network Address Translation NAT (Network Address Translation) has been widely used, but if the words run together, will encounter many problems. From the perspective of IP, NAT to the IPs were revised lower, to the IP protocol, it is a departure; and TLP181 price and from the application point of view, network managers have to deal with the problem of network addresses, NAT allows the user to take a variety of ways to their own network and TLP181 suppliers and the host of the external public network hiding is a good tool, now, whether large or small and medium enterprises are in use. And NAT, like, IPSec: is also a good tool, he can safely allow users to connect through the Internet to a remote terminal. However, the IPSec protocol architecture itself and the lack of support for IPSec, NAT devices, when the IPSec and NAT will be running with a lot of problems. To solve the problem of coexistence between the two, it is necessary for IPSec and NAT have a certain understanding.
