Sam, I'm seeking elaboration on "Stuart explanation". What I remember is a high-level "configuring two ports is harder than configuring one". Maybe more was said but I couldn't capture it. In the interest of time in the call I didn't go after it. You seem to have an understanding of it , since you are referring to it. Can you elaborate on the issue?

What's the firewall issue? 

You are just naming the issues "Firewall issue", "Stuart issue". Can you expand them a bit beyond their titles?
