Hardware:
1. It is necessary to clarify the hardware principles of a small home router (one WAN interface, four LAN interfaces).
2. Realize the hardware circuit board design, complete the circuit wiring design, solder the components, and debug the hardware board.
Software:
1. Based on the analysis of the uClinux kernel source code, tailor the kernel of the uClinux operating system.
2. Complete the configuration of BoaWeb server and design the CGI script to complete the function of dynamic web pages.
3. Configure PPPOE dial-up.
4. For the Linux kernel firewall, use the IPtable tool to operate firewall rules.
With the above basic structure, a router is basically formed. It sounds simple, but it contains many technical details and requires a lot of practical experience to truly implement it.
A router (also known as a router) is a computer network device that can transmit data packets to the destination through each network (selecting the transmission path of the data). This process is called routing. A router is a device that connects two or more separate networks. Routing works on the third layer of the OSI model - the network layer, such as the Internet Protocol (IP) layer.
