Proxy Server Doesen't work

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

Internet Protocols

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.
