09/07/2011 · PPTP - Same as PPPoE, This option is mostly used by DSL service users with provided username, password and IP information. L2TP - This option is mostly used by DSL service users is Europe with provided username, password and L2TP server information. L2tp is primarily for vpn it is a combination of pptp and cisco's l2f or layer 2 forwarding. GRE is cisco's generic route epcapsulation basically creating an ip tunnel to carry "other" traffic accross an ip backbone. it must be terminated on the outside or closet points of the tunnel. dans ppp, il n'y a que l'echange pap qui transmet le mot de passe en clair. Mais quand on peut (toujours maintenant), c'est chap qui est utilisé, donc mot de passe crypté. Merci Dans le domaine des réseaux, le protocole PPP (en anglais, Point-to-Point Protocol) est un protocole de communication utilisé communément pour établir une connexion directe entre deux noeuds à travers un câble série, une ligne téléphonique, une ligne de jonction, une communication téléphonique sans fil, une liaison radio spécialisée ou une liaison par fibre optique. User multiplexing in a single PPP/PPPoA session vs. PPPoE session multiplexing. Dirk Van Aken Gert Marynissen Stan Claes Date: December 2000 Ed: 4 Abstract This paper describes two methods that are used with ADSL modems to provide ”dial–up” type of
User multiplexing in a single PPP/PPPoA session vs. PPPoE session multiplexing. Dirk Van Aken Gert Marynissen Stan Claes Date: December 2000 Ed: 4 Abstract This paper describes two methods that are used with ADSL modems to provide ”dial–up” type of connections. In the first section a brief introduction is given into PPP protocol operation. Next two rather new PPP encapsulation methods
PPTP. PPTP has become quite popular because unlike OpenVPN it doesn’t require additional third-party client software to run on. PPTP requires a control channel over TCP as well as an operation GRE tunnel in order to encapsulate its PPP packets. The majority of operating systems, which include Microsoft
The MikroTik RouterOS has a RADIUS client which can authenticate for PPP, PPPoE, PPTP, L2TP and ISDN connections. The attributes received from RADIUS
點對點隧道協定（英語： Point to Point Tunneling Protocol ，縮寫為PPTP）是實現虛擬私人網路（VPN）的方式之一。 PPTP使用傳輸控制協定（TCP）建立控制通道來傳送控制命令，以及利用通用路由封裝（GRE）通道來封裝對等協定（PPP）封包以傳送資料。 PPPoE vs. PPTP. vnvnvn2000 Member Posts: 3 March 2009 in Network+. Hello all, For the W-ISP I work for, I have decieded that for security and control we will be using either PPPoE or PPTP to give our customers access to the PPP is a layer-2 protocol, but PPTP basically allows you to extend a LAN on top of other protocols. As you wrote, it is above layer-4, and the layer-2 protocol used when using PPTP could be PPP. Unfortunately protocols above layer-4 are explicitly off-topic here. PPP: (Point-to-Point Protocol) Une connexion PPP peut appeler des réseaux distants par l'intermédiaire d'un serveur PPP standard de l'industrie. PPP permet à un SAD (serveur d'accès distant) de recevoir des appels entrants et de garantir l'accès au réseau à des logiciels d'accès distant d'autres éditeurs, conformes aux normes PPP. PPTP (англ. Point-to-Point Tunneling Protocol) — туннельный протокол типа точка-точка, позволяющий компьютеру устанавливать защищённое соединение с сервером за счёт создания специального туннеля в стандартной, незащищённой сети. Writing a Driver to Capture PPP Frames. 05/31/2018; 2 minutes to read; In this article. When Point-to-Point Protocol (PPP) frames are sent through a Point-to-Point Tunneling Protocol (PPTP) tunnel with encryption turned on, or through a Layer 2 Tunneling Protocol (L2TP) tunnel that uses IPSec for encryption, the typical PPP frame capture utility can only capture PPP frames that have an PPTP folosește un canal de control peste TCP și un tunel GRE pentru a încapsula pachetele PPP. Specificația PPTP nu descrie metode de criptare sau autentificare, ci se bazează pe faptul că protocolul PPP este tunelat pentru a implementa securitatea.
Sécurité : PPTP n’est pas un VPN sécurisé, mais il reste difficile à décrypter. PPTP convient bien pour une sécurité complémentaire. Comment fonctionne PPTP. PPTP crypte, authentifie, et compresse le PPP, ainsi que toutes les données qui sont transférées, et les place dans une enveloppe IP.
L'utilisation d'un protocole de « tunneling » comme L2TP (ou PPTP) peut s'avérer un moyen pour assurer le transport de PPP sur IP, mais ajoute une complexité

Microsoft Point-to-Point Encryption (MPPE) encrypts data in Point-to-Point Protocol (PPP)-based dial-up connections or Point-to-Point Tunneling Protocol (PPTP) virtual private network (VPN) connections. 128-bit key (strong), 56-bit key, and 40-bit key (standard) MPPE encryption schemes are supported. 點對點隧道協定（英語： Point to Point Tunneling Protocol ，縮寫為PPTP）是實現虛擬私人網路（VPN）的方式之一。 PPTP使用傳輸控制協定（TCP）建立控制通道來傳送控制命令，以及利用通用路由封裝（GRE）通道來封裝對等協定（PPP）封包以傳送資料。 PPPoE vs. PPTP. vnvnvn2000 Member Posts: 3 March 2009 in Network+.
