title: How do I setup multiple Squid proxies on the same EC2 instance?
body: <p>I'm trying to setup multiple Squid proxies on a single EC2 instance.</p>
  
  <p>I've followed this <a href="https://askubuntu.com/a/680691">https://askubuntu.com/a/680691</a> but I can't seem to get it working.</p>
  
  <p>I have assigned two elastic IPs to the instance. I can connect to the first IP as a proxy but the second one fails.</p>
  
  <p>Here is my squid config:</p>
  
  <pre><code>http_port 172.xx.xx.215:3128 name=3128
  http_port 172.xx.xx.64:3129 name=3129
  
  acl tasty3128 myportname 3128 src 172.xx.xx.0/20
  http_access allow tasty3128
  tcp_outgoing_address 172.xx.xx.215 tasty3128
  
  acl tasty3129 myportname 3129 src 172.xx.xx.0/20
  http_access allow tasty3129
  tcp_outgoing_address 172.xx.xx.64 tasty3129
