3. Introductions Presenter – Ronald Beekelaar Work MVP Security
MVP Virtual Machine Technology
Beekelaar Consultancy BV
Work
Security consultancy
Virtualization consultancy
Create many VM-based labs and demos
Software to optimize, manage and run VM

4. Session Objectives Main goals:
Make it easier for you to talk to customers about using the remote access and management solution of DirectAccess in combination with Unified Access Gateway
Or: implement DirectAccess in combination with Unified Access Gateway in your own organization
How to do that?
Help understand the function of DirectAccess (DA)
Understand relationship between UAG and DA
Know that UAG DirectAccess + IPv6 + IPsec is "easy"
Sub goal:
Use the lab environment for demos

6. What is DirectAccess
Connect with roaming client "directly" to the company network
No VPN needed
No extra IP address needed
No terminal server "trick"
Use same "internal" server names: \\hrserver1,
Requires IPv6 addresses
Also: connect from company network to roaming client computer – even before user logs on

7. IPv6 ? Successor to IPv4, but not well-understood
Multiple transition techniques to have IPv4 plus IPv6

8. Technologies used Internal network External network (Internet)
Isatap: automatically map ipv4 to ipv6
External network (Internet)
6to4 tunneling or
Teredo or
IP-HTTPs

9. UAG DirectAccess
Provides DirectAccess 'access' to IPv4 servers on the company network
Is IPv6 "isatap" router on company network
Implements DNS64 and NAT64

10. DNS64 and NAT64 - say"6-to-4"
From: deep-dive-into-directaccess-nat64-and-dns64-in-action.aspx

11. Terminology "Cheat sheet"
IPv6 addresses
fe80: - link-local (no routing) ~~ x.x
2002: - 6to4 (with routing)
2001: - Teredo addresses
Transition
Isatap - generates link-local IPv6 based on IPv4
6to4 - tunneling on Internet
Teredo - (if NAT) uses UDP 3544
IP-HTTPs - when no Teredo possible
