PPTP VPN
This protocol allows you to implement a secure point-to-point connection by creating a tunnel in an insecure network.
The work of PPTP is to implement PPP frames in IP packets for transferring them to any IP network, including the Internet. In addition, this technology can be used to create a tunnel between local networks.
A TCP connection is used to service the created PPTP tunnel.
Brief specification
The protocol specification was published in 1999 in RFC2637, but the IETF community has not ratified it.
Less secure than IPSec, PPTP establishes a PPP session using the GRE protocol. The 1723 TCP port is used to control and initiate the GRE connection. Redirecting PPTP to the firewall is difficult because the protocol requires two sessions to be established simultaneously. Continue reading
Connect Xbox 360 via VPN server
Regional content protection checks your account for belonging to a specific country, and checks it against the IP address of your console. If your account is American, and the IP address belongs to any other country, then you won’t be able to download content intended only for USA. We will describe the options for solving this problem using a VPN below.
Using a router
One of the options, which may also be the simplest, is to set up a VPN on the router and give them Wi-Fi to the XBOX. But we want to immediately warn that with some routers it may not work. Although it’s worth a try.
If in the settings of the router the section with VPN is not occupied by your provider, then just enter the settings of our VPN there. Continue reading
VPN Basic Concepts and Classification
The term VPN (Eng. “Virtual Private Network”) refers to a group of technologies that provide a network connection, or the so-called logical network, functioning on top of some other network, usually the Internet.
Although data is transferred to a VPN over networks with a low level of trust, thanks to the use of cryptography, the level of trust in a VPN can be arbitrarily high. Among the cryptography tools used are encryption, means to protect against changes in transmitted messages, public key infrastructure and authentication. Depending on the final destination, the VPN implements three types of connections: network-to-network, node-to-network and node-to-node.
VPN implementation and structure Continue reading
