SSLVPN, IPSEC, PPTP, L2TP, etc., etc., allow users to pass one-click operation It is convenient and fast to establish a low-quality wide-area online private network, providing a wide area network security business transmission channel, facilitating the company's headquarters and mobile staff, branch, partners, product suppliers, customers, improvement Branches, customers, suppliers, and partners have the ability to carry out business. Provide a full range of local area network management solutions through its own DHCP server, ARP firewall, DDNS and other functions. All-round LAN access security management scheme. Products provide functions such as firewall, anti-virus, intrusion detection, user access to active certification, etc. Access to the company via routing, NAT, multi-link multiplexing and detection. Enter the company to solve the flexible expansion of bandwidth and inexpensive access. Wideband access scheme, realize flexible expansion bandwidth and inexpensive access. Product support ADSL, Optical fibers, etc. The gateway address on the computer will be filled in 192.168.0.1 Features Other hosts must also be 192.168.0.x (any number between 2-254) so that the router can be accessed, which is said to go online. The IP is 192.168.0.1 (this is the gateway) is also the address necessary for the router. The gateway is an IP access to the router, and other computers must be able to access routers with an IP segment of the gateway, such as routers. The difference between the gateway and the router: According to the seven-layer level limit, the high-level agreement can take the principle of the low-level agreement, and the development of the security gateway is going to the line of the high-level agreement. The safe gateway of the anti-drug wall acts in the second layer. The security gateway has a firewall figure on the application layer and the network layer, and the VPN function can be seen on the third floor. I simply introduce these 7 layers and its functions.Īmong them, The 7, 6, 5, and 4 layers define the functions of the application, the following 3, ie 3, 2, 1 layer mainly facing the end-to-end data stream through the network. The OSI model has a 7-layer structure, and there are several sub-layers per layer. OSI is an open traffic system interconnect reference model, he is a definition Good agreement.
Gateway at the seven-layer protocol of the application network:
