Linux shared Internet Settings

1. Turn on kernel ip forwarding

Vi / etc/sysctl.conf net.ipv4.ip_forward = 1

The execution of sysctrl-p takes effect.

2. If the host does not have a firewall enabled, set iptables as follows

[root@Web-Lnmp02 ~] # iptables-F [root@Web-Lnmp02 ~] # iptables-P INPUT ACCEPT [root@Web-Lnmp02 ~] # iptables-P FORWARD ACCEPT [root@Web-Lnmp02 ~] # iptables-t nat-A POSTROUTING-o eth0-j MASQUERADE or iptables-t nat-A POSTROUTING-s ip-o eth0-j MASQUERADE / / specify an ip or ip segment that can forward iptables-t nat-A POSTROUTING-s 192.168.0.170-o enp1s0-j MASQUERADEiptables-t nat-A POSTROUTING-s 192.168.0 filter 24-o enp1s0-j MASQUERADE [root@Web-Lnmp02 ~] # / etc/init.d/iptables save [root@Web-Lnmp02 ~] # / etc/init.d/iptables restart description: iptables-F # clears the rules in the original filter iptables-t nat-F # clears the rules in the original nat table iptables-P FORWARD ACCEPT # allows IP forwarding by default

If a firewall is enabled on the host, add the following two sentences:

Code:

Iptables-A FORWARD-s 192.168.122.0 FORWARD 24-o eth0-j ACCEPT iptables-A FORWARD-d 192.168.122.0 eth0 24-m state-- state ESTABLISHED,RELATED-I eth0-j ACCEPT is all the contents of this article entitled "how to set up shared Internet access in linux".
