IT Interview Questions:How do you allow inbound traffic for specific hosts on Windows 2003 NAT?
IT Interview Questions:How do you allow inbound traffic for specific hosts on Windows 2003 NAT? What is VPN? What types of VPN does Windows 2000 and beyond work with natively?
Microsoft defines a virtual private network as the extension of a private network that encompasses links across shared or public networks like the Internet. With a VPN, you can send data between two computers across a shared or public network in a manner that emulates a point-to-point private link (such as a dial-up or long haul T-Carrier-based WAN link). Virtual private networking is the act of creating and configuring a virtual private network. To emulate a point-to-point link, data is encapsulated, or wrapped, with a header that provides routing information, which allows the data to traverse the shared or public network to reach its endpoint. To emulate a private link, the data is encrypted for confidentiality. Packets that are intercepted on the shared or public network are indecipherable without the encryption keys. The link in which the private data is encapsulated and encrypted is a VPN connection. There are two key VPN scenarios
remote access and site-to-site. In remote access, the communications are encrypted between a remote computer (the VPN client) and the remote access VPN gateway (the VPN server) to which it connects. In site-to-site (also known as router-to-router), the communications are encrypted between two routers (VPN gateways) that link two sites.
