device to add two subnets at the same time, with Iptables's masquerade function to proxy a subnet device to access another subnet. Masquerade A more commonly used name is NAT. Basically all the home wireless routers are the network of this mode.There is an essential difference between a wireless relay router and a common network of home wireless routers. Ordinary wireless routers generally walk on the ADSL PPPoE, which is the wired network. The downside is to share the Internet of wired network

The former is called "Static VLAN", and the latter is naturally "dynamic VLAN".A static VLAN, also known as a port-based VLAN (portbased VLAN). As the name implies, it is the setting that explicitly specifies which VLAN each port belongs to. 、Dynamic VLANs Change the VLAN that the port belongs to at any time, depending on which computer is connected to each port. This avoids actions such as the above change settin

Compare the OSI seven layer model and the TCP/IP four layer model The OSI seven-layer model enables reliable communication between different networks of different systems through seven hierarchical structural models, so its main function is to help different types of hosts achieve data transfer. The nodes that complete the relay function are often referred to as trunking systems. In the OSI seven layer model, the relay systems at different tiers
