Limitations and precautions for the USG9000

4

The limitations and precautions for the USG9500 are as follows:
-The USG9500 supports license application based on the ESN of the MPU or the backplane. It is recommended that the ESN of the backplane be used to apply for a license. Because you need to apply for a license again if you replace a faulty MPU whose ESN is used to apply for a license.
-In dual-MPU mode, if you use the ESN of an MPU to apply for a license, you must provide the ESNs of both active and standby MPUs.
-In dual-MPU mode, the license files, license file names, and license file storage paths of both MPUs must be the same. Otherwise, service interruption may occur upon MPU switchover.

NAT on the USG9000 series
NAT is a type of address translation technology that converts the address in an IPv4 packet header into another address. Generally, the NAT technology is used to convert private addresses in IPv4 packet headers into public addresses so that users on the private network can access the Internet concurrently by using a few public addresses. The NAT technology is usually used to address the issue of public IPv4 address shortage caused by the constant increase in the Internet scale.
