Reverse Proxy is a proxy server that allows Internet users to access servers on the internal network.

192.168.0.4 contains two NICs, one is a public ip address and the other is 192.168.0.4.

Two services on two servers inside and outside the proxy are running on port 9000 and port 81 respectively.

01) install Apache2:
Sudo apt-get install apache2
Test Access: 192.168.0.4

02) restart the server:
Sudo/etc/init. d/apache2 restart

03) virtual host + reverse proxy configuration:

Objective: To use the ip address 192.168.0.4 of the server where apache2 is installed as the proxy to run the tomcat server on 192.168.0.15: 9000
Prerequisites:
Apache2 is installed on 192.168.0.4 and can be accessed normally.
192.168.0.15: 9000 can also be accessed normally
