Apache webservers behind load balancer - restrict them to only serving traffic to the load balancer
Posted on 2014-10-30
Hi, we have a few apache webservers behind a couple of load balancers.
I would like to make sure that the only web traffic that occurs is coming from the load balancers... So basically I don't want someone who knows the IP-Address of the server to be able to send http/https requests to the server via it's ip address instead of going through one of the load balancers.
I am guessing it isn't overly complicated to do this, I just need to know how to do it. We are running Apache on a Debian Linux system.
