This configuration of apache is a little specific to forwarding all requests coming to a custom port on the host system to a local system which maybe running a service on custom port.<\/p>\n\n\n\n
Let us say we have 2 systems. System A and B where A can be accessed from the internet on lets say port 8084 and system B which is in the local system is hosting a service on port 8700. Now if someone from outside wants to access B:8700 then they can not do it directly unless we find a way to redirect requests to it from the public facing system A. Apache reverse proxy comes handy to do the job and it is relatively easy to configure.<\/p>\n\n\n\n
The following setup is tested on debian bullseye with apache 2.4. The same may work on other systems to as it is fairly simple to setup.<\/p>\n\n\n\n
On system A<\/p>\n\n\n\n
First make sure apache is installed and running if not install it with apt-get install apache2. Then follow these steps.<\/p>\n\n\n\n
Restart apache 2. Enable custom port in \/etc\/apache2\/ports.conf<\/p>\n\n\n\n Listen 80 3. Now create a file for virtualhost in \/etc\/apache2\/sites-available\/proxy.conf and add these lines. You may change the ports and local ip according to your setup.<\/p>\n\n\n\n Restart apache and test with public IP:8084. the traffic should be going to system B which is at 192.168.3:8700. <\/p>\n\n\n\n I took help from these sources<\/p>\n\n\n\n https:\/\/www.digitalocean.com\/community\/tutorials\/how-to-use-apache-http-server-as-reverse-proxy-using-mod_proxy-extension<\/a><\/p>\n\n\n\n https:\/\/www.mirantis.com\/blog\/quick-tip-use-apache-as-a-proxy-server-to-access-internal-ips-from-an-external-machine\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" This configuration of apache is a little specific to forwarding all requests coming to a custom port on the host system to a local system which maybe running a service on custom port.
