Multi-host internet based on a public network IP

First, let's talk about the server architecture I deployed:

One LVs, one tomcat, one MySQL (pre-deployment).

1, the company gave me a public network IP, in the LVS used this IP, but Tomcat Internet has become a

Problem, here's a solution, hopefully to help you:

The first step: the LVS on a network card is set to public IP, the other piece is set to private network IP (for example, 192.168.1.100).

The second step: the LVS need to turn on the Ip_forward forwarding function. (Note: IP forwarding is to enable multi-host Internet access in the location)

Step three: Tomcat needs to set the gateway to 192.168.1.100 so you can ping the LVS on

The public network IP address, if not, first resolved.

Fourth step: Use Iptables to do Snat on LVS:

Iptables-t nat-a postrouting-s 192.168.1.0/24-o eth0-j SNAT--to-source public network IP

Fifth step: Finally, you need to do a DNS configuration on the machine you need to surf the internet, just add the/etc/resolve.conf

NameServer 8.8.8.8 will be all right.
