Hoping someone with hands on experience configuring Manage Out functionality can answer a few questions for me?

We have built a Server 2012 VM and deployed DirectAccess successfully.  Have tested with both Win7 and Win8 clients successfully.  After some initial issues with DNS were addressed with a Microsoft hotfix, it seems to be running stable.

I want to configure Manage Out capabilities, so that I can remotely help the DA clients with software installs and similar.  I've read up on as many blog entries as I can find, but still finding it a bit mystifying. 

We are using IP-HTTPS connectivity.  As best I can tell, we are not using Teredo or ISATAP.  The DA server is dual-NIC and is configured behind an Edge device (NIC #1 is DMZ and receives NAT'd traffic from external IPv4 address on firewall, NIC #2 is internal LAN).  Our internal networks are IPv4 only (no IPv6 at all); therefore DNSv4 and DHCPv4 internally).

Am hoping that somewhere there might be a step-by-step configuration guide to match our scenario.  Alternatively, if someone can recommend a Local (i.e. Melbourne, Australia) consultant who knows this stuff backwards, I'd consider paying for that.
