Install Foreman on EC2

I'd like to install forman on EC2. Actually, I have. The problem is, I
can't access it without a VPN.

I don't actually have a domain pointing at any Public IP from Amazon, at
the moment.

what I'd LIKE to do, is have the Foreman instance on EC2, access it just by
public IP, and have it manage the nodes in the VPC that it is installed in.
Is this possble withut installing a VPN?
