hello, if my office blocks VPN outgoing connection (port 1723), is it possible to do this? <br />
<br />
1)Pc1 - VPN client dials localhost port 1723<br />
2) Pc1 - TCP redirection software redirects that connection to remove VPN server port 80<br />
3) VPN server - accepts that connection<br />
4) VPN server - TCP redirection software redirects that connection to itself to port 1723<br />
<br />
I have a TCP/UDP redirection software. I telnet to those ports, seems connection can be established, but when i try to VPN-dial, I get &quot;Error 800 : Unable to establish the VPN connection&quot;.<br />
<br />
is VPN not TCP connection ? or is it much more complicated than that?

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

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
