Microsoft UAG DirectAccess vs. Windows Server 2012 DirectAccess

DirectAccess was first introduced as a feature within Windows Server 2008 R2 and Windows 7 Client.  DirectAccess overcomes the limitations of traditional VPN connectivity by automatically establishing a bi-directional connection from client computers to the corporate network wherein users never have to manually establish a connection to the enterprise network.  The biggest advantage of DirectAccess is that IT administrators can manage remote computers outside the office just as they would manage machines connected inside the corporate network.  For more information, please visit: http://www.napplianc

Single Sign-on for Office365 with Forefront TMG

In my first contribution to the Forefront Security blog, I will explain how to extend the Office 365 single sign-on experience to remote users by publishing ADFS 2.0 with Forefront TMG.   

(Single sign-on allows users to use their corporate (Active Directory) user ID and password in order to access Office 365 services located in the cloud).

Can I use the Mac OS to create a Remote Desktop connection published through the UAG?

Most of our customers who have UAG appliances deployed also have a few Mac machines in their organizations and the issue of whether remote desktop connections can be used is something which comes up frequently on sales or technical calls.

Your computer can't connect to the remote computer because the Remote Desktop Gateway server reached its maximum allowed connections. Try reconnecting later or contact your network administrator for assistance

Adding OTP AUthentication to the UAG DirectAccess Deployment

DirectAccess is a seamless way to connect to company resources without dialing or logging into any other server. The default configuration of the DirectAccess uses Kerberos and certificates to create IPsec tunnels for a secure connection. So, how does it work? Well, the user connects their Windows 7 machine to the internet and machine creates the first IPsec tunnel, called the “Infrastructure Tunnel,” with the DirectAccess server.

Application Publishing in TMG

One of many good features in Microsoft TMG is the ability to publish internal web based and non-web based applications on the internet for corporate users to access remotely. Users can access applications such as Outlook Web Access, SharePoint, CRM, RDP, and Citrix as they are published through the Microsoft TMG server. There are two types of publishing in the TMG:

SharePoint publishing through TMG vs. UAG: Capabilities and Benefits

Many of our customers wonder if it is better to use TMG or UAG for Sharepoint publishing, or whether either should be used at all. The answer, while not complex, involves some consideration of the relative capabilities and benefits of both pieces of software. In this post we will try to outline the key differences which will answer these questions. This post will give you a high level overview of the basic differences between the two.

We aren’t IPv6-ready yet, what do we need to deploy DirectAccess?

Every IT manager, when deciding on a strategy for deploying DirectAccess for their corporate users, has the following questions on their mind about IPv6:

When you have no excuse to not deploy Microsoft DirectAccess

As we have described in a previous blog post, Microsoft DirectAccess has many benefits over traditional VPN: http://www.nappliance.com/blog/nappliance-nuag-and-directaccess-better-together.

What role does DNS64 and NAT64 play in UAG Direct Access?

By now, most of us know what DirectAccess is. For those who don’t, Direct Access is a revolutionary VPN technology which was introduced in Windows Server 2008 R2. It provides seamless connectivity to corporate resources without requiring any dial-up or VPN. DirectAccess connectivity is based on IPsec, IPV6, and transition technologies like Teredo, 6to4, IP-HTTPS, and ISATAP. In DirectAccess, the IPv6 traffic is encapsulated in an IPv4 packet and is then sent across the internet, after which the DirectAccess server reads the IPv6 headers and executes it.
