Description

Anti-violation external connection audible and visual alarm

Technical Field

The utility model relates to the technical field of alarm devices, in particular to an anti-violation external audible and visual alarm.

Background

The intranet is a local area network, and computers in the intranet access the Internet through a public gateway by using an NAT (network address translation) protocol. The computer of the intranet can send a connection request to another computer on the Internet, but the other computer on the Internet cannot send a connection request to the computer of the intranet.

NAT (network Address translator) is network Address translation, and realizes the mutual translation between the IP Address of the internal network and the Address of the public network, thereby translating a large number of IP addresses of the internal network into one or a small number of IP addresses of the public network and reducing the occupation of the IP addresses of the public network. The most typical applications of NAT are: in a local area network, only one computer is connected with the Internet, and the NAT can be used for sharing the Internet connection, so that other computers in the local area network can also surf the Internet. Using the NAT protocol, computers in the lan can access computers on the Internet, but computers on the Internet cannot access computers in the lan.

The intranet usb device must not be plugged into the extranet interface, but some users are unaware of it, which causes unnecessary trouble.

Therefore, an anti-violation external audible and visual alarm is provided.
