addresses without virtual dialing. Web Interface Management: The current home routers are all web interface management, which is very convenient to use, just like accessing the Internet at ordinary times. These two functions are the most essential of a home Broadband Router, as long as it is a home Broadband Router, it is certainly supported. Summary Finally, let's talk about some interesting things: in fact, the vro also has CPU and memory, which is equivalent to a small computing, and also ha

-Link's home Wireless Broadband Router products are favored by many users because they have simple installation and configuration, and strong control capabilities, in particular, DI-624 + A this home Wireless Broadband Router has been the market selling products, design more to cater to the aesthetic concept of young people, the D-Link logo is prominently embedded in the middle of its black top, stable and generous. D-Link DI-624 + A wireless router supports 802.11g standard, external removable

speed of 533 MHz and complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x standards; supports TCP/IP, PPPoE, DHCP, ICMP, NAT, SNTP, DNS, TFTP, ARP, and other protocols; supports binding IP addresses to MAC to prevent unauthorized computer access to the network; supports network management functions such as IP Client filtering, domain name filtering, and MAC address filtering; supports Auto MDI/MDIX; supports port bandwidth control, port VLAN division, and Port Mirroring; supports

Add a broadcast route In this actual working environment, machines in the LAN are connected to the eth1 Nic of the Linux server through a switch. To broadcast the entire LAN on a Linux server, add the following route: # Route add-

configured as DHCP relay proxies. Let's take an experiment and look at the setting method. Experimental Platform: two servers with Linux system installed, one is the DHCP server Server1, the other is the dhcprelay relay Proxy Server Server2, and the other is the PC1 and PC2 used for testing. Lab environment: allocate three network segments: 192.168.10.0/24 192.168.20.0/24 Two NICs must be installed on the server used as the DHCP relay Proxy: eth0 and eth1. IP Address Allocation is as follows: E
