As a rule, VPNs are deployed by corporations, educational institutions and other organizations so that their users could access local resources from outside the territory and when connected to a wireless network. Protocols for building a VPN tunnel, a brief description IPsec- a set of protocols to ensure the protection of data transmitted over the Internet Protocol (IP) allows authentication and / or encryption of IP packets. IPsec also includes protocols for secure key exchange on the Internet. It is mainly used for organizing vpn connections. PPTP(English Point-to-Point Tunneling Protocol) is a point-to-point tunnel protocol that allows a computer to establish a secure connection to the server by creating a special tunnel in a standard, non-secure network. PPTP places (encapsulates) PPP frames into IP packets for transmission over a global IP network, such as the Internet. PPTP can also be used to establish a tunnel between two local networks. PPTP uses an additional TCP connection to maintain the tunnel. L2TP(English Layer 2 Tunneling Protocol - second level tunneling protocol) - in computer networks a tunnel protocol used to support virtual private networks. The main advantage of L2TP is that this protocol allows creating a tunnel not only in IP networks, but also in ATM, X.25 and Frame Relay networks. [1] Openvpn- a free implementation of open source Virtual Private Network (VPN) technology for creating encrypted point-to-point channels or server clients between computers. It allows you to establish connections between computers behind a NAT-firewall, without the need to change their settings. OpenVPN was created by James Yonan and is distributed under the GNU GPL license. Setting up a VPN connection on Android Configure VPN on Android 2.x Adding VPN:

Local [offline] Group: Friendssavagemessiahzine.com Messages 216 Check in: 13.09.07 Apple iPhone X Reputation: 10 | Also encountered a problem, I will describe what I did: At home, the Eee901 with WinXP Home is turned on around the clock, it has configured an incoming VPN connection with encryption (PPTP) and turned off the Windows firewall (it doesn’t really need it anyway). On the ADSL router, I configured port forward for PPTP and a client for Dynamic DNS, I have a dynamic IP. On the device (HTC Legend, Android 2.1), I configured the built-in VPN client and press "connect". Everything connects perfectly, from the communicator I see all the resources of the internal network - I can steer the router, for example. But the Internet addresses will not resolve from the communicator, if you enter the IP - pages open. In the VPN settings on the communicator, there is only "Network name", "server address", tick encryption and "DNS search domains" - I tried to enter the address of the router and the computer and even Google 8.8.8.8 to enter - it does not help. What to do? -------------------- Motorola p7389 ->Siemens C55 ->S55 ->S65 ->SE K750 ->W810 ->Nokia 6233 ->HTC Gene ->HTC Touch 3G ->HTC Legend ->HTC Wildfire S ->iPhone 4S ->iPhone 5 ->iPhone 5S ->iPhone SE ->iPhone 8 ->iPhone X -> ??? |

And then through the communicator to connect to it? And if, for example, I have an ordinary internet connection without a VPN, how it will turn to him, who could do it, plz step-by-step FAQ, thanks in advance |

Old resident [offline] Group: Friendssavagemessiahzine.com Messages 774 Check in: 29.03.10 Lenovo Moto G5 Plus Reputation: 40 | Kamikadz I must say that I did not succeed. Incoming VPN connection on the computer configured, configured the firewall, configured your router. Ordinary PCs join me normally, but the phone does not want to. How to configure the incoming VPN connection on the computer: Go to the network environment, where the list of connections. Click alt, file - incoming connection, select users who are allowed access (these users must have a password), configure the range of addresses that will be issued to users and that's it. On the PCs that will connect to you, you need to create an outgoing VPN connection, enter the server (address of your PC), start the connection, enter the username and password of the user, click connect. Important: your PC must have a real address, that is, it must be pinged from the Internet. -------------------- Samsung GT-I5700 Galaxy Spica (TurboSGM2.1 [Final_Release] [UPD3] byarssev1+ all2ext2 + swap 256 Mb + Link2SD 512 Mb)>Samsung GT-S7710 Galaxy Xcover 2 Black Red>Motorola G5 Plus Gray 3 / 32Gb |

Local [offline] Group: Friendssavagemessiahzine.com Messages 216 Check in: 13.09.07 Apple iPhone X Reputation: 10 | in the "DNS search domains" you need to add the address of the server of your Internet service provider Cellular operator or provider of wired internet? Wired tried - did not help. Cellular - just could not find DNS Beeline, who knows - tell me? As for the distribution of addresses connected via VPN - even XP Home normally distributes addresses. I only have a problem with the DNS service, so far it has not been possible to achieve normal operation. And so - on the internal network all the PCs are available, I can go to Popcorn and manage torrents and the player. -------------------- Motorola p7389 ->Siemens C55 ->S55 ->S65 ->SE K750 ->W810 ->Nokia 6233 ->HTC Gene ->HTC Touch 3G ->HTC Legend ->HTC Wildfire S ->iPhone 4S ->iPhone 5 ->iPhone 5S ->iPhone SE ->iPhone 8 ->iPhone X -> ??? |

In your case, this is a wired provider. Why does not work I do not know.

User [offline] Group: Friendssavagemessiahzine.com Messages 90 Check in: 16.11.08 HTC Hero Reputation: 0 | klyon DNS is also in Africa; DNS;) What is a provider, what is Google, eventually synchronizes the bases in one place, so there is no difference. The difference is only when you inside your network use your DNS server for the local network. In order for it to normally rezolvil external addresses, you need to configure forwarding DNS. Yma, The last phrase about forwarding is primarily for you. If internal ip rezolvitsya normally, configure your DNS server, to work correctly with external DNS servers. When working with VPN, all traffic goes to your router and there it is already decided what to do with it. Correct work VPN + DNS + DHCP is still that nontrivial task. |

In general, the DNS should be determined automatically, you need only enter the address of the server, and set the encryption settings, well, the login and password, of course, too |

Local [offline] Group: Friendssavagemessiahzine.com Messages 227 Check in: 07.09.08 Reputation: 3 | HTC Legend will soon be roaming, where 50 kilobytes will weigh about one dollar. How to turn off the internet guaranteed? Is it enough to remove the bird in the item: "Wireless networks" - "Mobile Internet"? Or is the lack of a bird in paragraph: “Wireless networks” - “Mobile network” - “Data transfer in roaming” enough? In any case, both settings do not relate to Wi-Fi, which I will use? thank |

Visitor [offline] Group: Users Messages 13 Check in: 17.08.09 Reputation: 0 | The legend has the problem of forwarding the GRE protocol or 1723 ports. You connect a piece of iron with a cord, you connect to a working VPN server, and it shows BOLT. On Noke worked without problems. |
