title: How to configure AWS ELB to block certain IP addresses? (known spammers)
body: <p>I am looking for a way to drop connections from known spam ip addresses on an Amazon's Elastic Load Balancer (ELB)?</p>
  
  <p>I am currently doing this at the web server level (multiple instances, running behind the ELB), but wondering if there is a way to do it at the ELB. This way, I can avoid configuring each web server instance for this.</p>
  
  <p>I typically pull the <a href="http://www.spamhaus.org/drop/drop.txt">Drop List</a> from Spamhause.org every day and update my web server configuration</p>
