Set up a Linux DHCP server. If it is a Ubuntu system, directly

# apt-get install dhcpd

Change the / etc/dhcpd.conf file after installation and add:

Option domain-name-servers 202.96.134.188202.96.134.133 ETS defaultMutual netmask time 600 maxim Musical time 7200 subnet 192.168.1.0 netmask 255.255.255.0 {range 192.168.1.2 192.168.1.200 option routers 192.168.20.1;}

DHCP is set up. Next, you need to set up one more IP for the Linux host and set the IPtable rules.

Sudo ifconfig eth0:1 192.168.20.1sudo sh-c "echo 1 > / proc/sys/net/ipv4/ip_forward" sudo iptables-A FORWARD-s 192.168.20.0 take 24-j ACCEPTsudo iptables-A FORWARD-I eth0-m state-state ESTABLISHED,RELATED-j ACCEPT

You can write the above statement to a script. If you need to execute it, you can turn on the sharing function.

The window machine only needs to be set to automatically obtain the IP (or set to 192.168.20.x network segment, the gateway is 192.168.20.1). The physical connection is through the hub.

The situation of each person is different, and everyone should modify it according to his own situation.

At this point, the study on "how to share the Internet with Linux" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
