I'm setting up an environment where I have a VM host running behind a NAT firewall and plan to install VMs with public IPs so that they can be directly accessed over the internet like in the following diagram.

How would you go about connecting these two VMs to the net and how would you configure the VM host? (bridging, etc)
I have a Rails app with the Devise authentication gem running user registration and login. I want to use the db table that Devise populates when a user registers as the table that Postfix uses to authenticate users.
The table has all the fields that Postfix may want for SASL authentication except that Devise encrypts the password using Blowfish before placing it in the database.
How could I go about getting Postfix/SASL to decrypt those passwords so that the user can be authenticated properly? Devise salts the password so I'm not sure if that helps.
Any suggestions? I'd likely want to do something similar with Dovecot or Courier, I'm not attached to one quite yet.
I've setup a Postfix + Courier server and have a Rails app configured with the SMTP server settings. Whenever the Rails app tries to send an email, this is what appears in the Postfix log (additional log verbosity set in master.cf)

Any ideas as to why it's losing the connection after authentication?
