Build DHCP and DHCP relay servers under RedHatLinux5

Experimental environment: the company's internal network is divided into three physical network segments, and each other is connected through a Linux gateway server. To provide centralized Address Allocation management, we need to build a DHCP server without increasing hardware investment, dynamically configure network parameters such as IP addresses for clients in different network segments (the experiment topology is as follows): Requirement Description: 1. enable route forwarding on the Linux gateway server and enable DHCP relay. 2. Build a DHCP server in the CIDR Block 192.168.1.0/24

Lab environment:

The company's internal network is divided into three physical network segments and connected to each other through a Linux gateway server. To provide centralized Address Allocation management, we need to build a DHCP server without increasing hardware investment, dynamically configure network parameters such as IP addresses for clients in different network segments (the experiment topology is as follows ):

Requirement Description:

1. Enable route forwarding on the Linux gateway server and enable the DHCP relay service.

2. Build a DHCP server in the CIDR Block 192.168.1.0/24 with the IP address 192.168.1.2. Network parameters, such as IP addresses, can be automatically assigned to clients in the 192.168.1.0/24,192.168 .2.0/24,192.168 .3.0/24 network segment.

3. dynamically assigned IP addresses for each client. The default lease time is 21600 seconds (6 hours), and the maximum lease time is 43200 seconds (12 hours ).

4. Set the DNS server address for each client to 202.106.0.20 and 202,106,148.1.
