title: Access a second EC2 instance in AWS VPC
body: <p>I've been looking around, but haven't been able to find much. It all seems to assume that I'm trying to access a single EC2 instance under a VPC.</p>
  
  <p>The scenario: We have one EC2 medium under a VPC which is hosting several websites (running Windows), and we need to launch a Linux EC2 under that same VPC to run a forum for one of the sites. It's going to run at <code>domain.com/forum</code> where <code>domain.com</code> is hosted on the Windows server. I'm going to try using a reverse proxy in IIS to get the forum, but we need to access it first. Would a NAT instance be what I'm looking for?</p>
  
  <p>Any ideas?</p>
