Forefront UAG 2010 Addresses DirectAccess Shortcomings
Microsoft's Forefront Unified Access Gateway 2010 helps DirectAccess move beyond pilot projects to actual network deployment.
Microsoft's Forefront UAG 2010 makes DirectAccess Feasible . Each has its own shortcomings and limitations, but UAG will interoperate with third-party solutions to further extend the reach and scale of DirectAccess. According to this eWeek report, Microsoft's Forefront Unified Access Gateway 2010 addresses many of the shortcomings of the DirectAccess by providing sorely needed measures of performance and availability scaling.
"Into the breach steps UAG, which addresses each of those concerns. Administrators who install UAG on each DirectAccess server in the network (thereby creating UAG DirectAccess servers) can scale DirectAccess management and performance beyond a single server by creating an array to aggregate all the servers. UAG's NAT64 and DNS64 implementations provide DirectAccess connectivity to IPv4-only intranet servers and applications, while SSL (Secure Sockets Layer) VPN functionality provides access to remote clients using older operating systems or to those not joined to the domain."
