the NAT Function to convert the IP addresses inside the LAN to valid IP addresses for Internet access. For example, a computer with an IP address 192.168.0.1 can communicate with other computers in the LAN, then, you need to use the NAT Function to convert 192.168.0.1 to a valid Wan IP address, such as 210.113.25.100.DHCP: The full name is Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol). Through the DHCP function, the router can dynamically specify IP addresses for hos

so far, and their functions and performance have been greatly expanded and enhanced. At present, home routers have more and more functions, such as DDNS, NAT, and VPN. For some users who are familiar with vrouters, reading these terms is simply reading tianshu. How can we make the purchased vrouters play their expected performance? Below I will introduce some common performance parameters of the vro to the readers, hoping to help users who first know

Add a broadcast routeIn 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 -host 255.255.255.255 -dev eth1 Add the preceding route to/etc/rc. local. The route can be automatically added even if the Linux server restarts.3. Configur

So let's take a look at the specific content. 1. DHCP server startup script --/etc/rc. d/init. d/dhcpd This script can be used to start, query, and stop DHCP servers. Configure the DHCP server before starting the instance. 2. Configure the DHCP server (1) DHCP configuration file --/etc/dhcpd. conf RHEL5 is a blank file by
