I have two Apollo's and I've upgraded both of them to the latest update with one running a full node. It's only been up for a short time and it's showing 9 connections so it looks like everything is working correctly (I also noticed the node count for futurebit went up by one, so I'm hoping that's me!!!  )
My question is, can I run another node on my other Apollo? Would it work since they're both behind the same firewall? Can you have multiple nodes behind a single firewall without having multiple public IP addresses?
