Setup is this. DM=SBS 2003, Citrix Access Essentials is used via TS for remote facilities to access server hosted applications. The remote facilities are connected using VPN tunnels via Sonic Wall. Internal access is established by accessing a secondary IP on the Citrix server. External access is used via https registered subdomain. I need to allow all authenticated users access to the Citrix server via VPN tunnel (using TS). This is how it is currently setup. I also need to restrict at the same time some of the same users access via https (from home) without restricting them while they are at the facility (using the VPN). The problem Im having is I can restrict TS for a user account but that will also prevent them from using TS while they are accessing via VPN tunnel. I dont know if im complicating a simple issue or if what is requested, not possible.

Restrict External TS access via SBS2003/Citrix Access Essentials

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Citrix is the synonym for the virtualization and application infrastructure systems developed by the company of the same name. Main areas are application virtualization, Software-As-A-Service (SaaS), cloud-computing and networking. The two most well-known are Citrix XenApp or Citrix CloudPlatform.
