  1. DirectAccess withUnified Access Gateway (UAG) Ronald Beekelaarronald@beekelaar.com

  2. Introductions • Presenter – Ronald Beekelaar • MVP Security • MVP Virtual Machine Technology • E-mail: Beekelaar Consultancy BVronald@beekelaar.com • Work • Security consultancy • Virtualization consultancy • Create many VM-based labs and demos • Software to optimize, manage and run VM

  3. 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

  4. Demo and Lab Environment • For study, testing, demo, POC, etc • Download from: • http://go.microsoft.com/fwlink/?LinkId=190269 • Contains all Forefront products • Including FIM and AD FS

  5. 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, http://portal • Requires IPv6 addresses • Also: connect from company network to roaming client computer – even before user logs on

  6. IPv6 ? • Successor to IPv4, but not well-understood • Multiple transition techniques to have IPv4 plus IPv6 Company network Internet IPv6 in IPv4 ? ? ? IPv4 IPv6 IPv4 IPv6 IPv4 IPv6 ??

  7. Technologies used • Internal network • Isatap: automatically map ipv4 to ipv6 • External network (Internet) • 6to4 tunnelingor • Teredoor • IP-HTTPs

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

  9. DNS64 and NAT64 - say"6-to-4" From: http://blogs.technet.com/edgeaccessblog/archive/2009/09/08/deep-dive-into-directaccess-nat64-and-dns64-in-action.aspx

  10. Terminology "Cheat sheet" • IPv6 addresses • fe80: - link-local (no routing) ~~ 169.254.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

  11. Networking in lab environment Company network Internet
