title: How to grant internet access to application servers through load balancer
body: <p>I have setup an environment in Jelastic including a load balancer (tested both Apache and Nginx with same results), with public IP and an application server running Univention UCS DC Master docker image (I have also tried a simple Ubuntu 20.04 install).</p>
  <p>Now the application server has a private IP address and is correctly reachable from the internet, also I can correctly SSH into both, load balancer and app server.</p>
  <p>The one thing I can't seem to achieve is to have the app server access the internet (outbound traffic).</p>
  <p>I have tried setting up the network in the app server and tried a few Nginx load-balancing configurations but to be honest I've never used a load balancer before and I feel that configuring load balancing will not resolve my issue (might be wrong).</p>
  <p>Of course my intention is to learn load balancing but if someone could just point me in the right direction I would be so grateful.</p>
  <p>Question: what needs to be configured in Jelastic or in the servers to have the machines behind the load balancer access the internet?</p>
  <p>Thank you for your time.</p>
