The MikroTik RouterOS has a RADIUS client which can authenticate for PPP, PPPoE, PPTP, L2TP, OpenVPN and ISDN connections. The attributes received from 

Layer 2 tunneling protocols; PPTP & L2TP are based on well-defined PPP protocol with useful features. These useful features & their Layer 3 counterparts;  PPP stands for Point-to-Point Protocol. 2.

SLIP covers  16 Oct 2019 Both PPTP and L2TP use PPP protocol to encapsulate data, and then add additional headers for data transmission on the Internet.

07/07/2020 The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks.PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality.. The PPTP specification does not describe encryption or authentication

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。 這個協定最早由微軟等廠商主導開發，但因 … 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 internet. I have a miniature prototype setup and I like the results. Currently using roaring penguin's pppoe-server with freeradius I have dynamic IP's, one simulatenous 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 frames are not wrapped in IP packets. It is the other way around; IP packets can be wrapped in PPP (or other layer-2 protocol PPP, pour faire dans le très grosso modo, c'est le protocole point à point qui est utilisé pour se connecter à internet et PPPoA c'est du PPP dans de l'ATM PPPoE c'est du PPP dans de l'Ethernet grosso modo, les trames PPP sont encapsulées dans d'autres protocoles . maith.

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. Totuși, implementarea cea mai comună a protocolului, care este livrată cu sistemul de operare Microsoft Windows, are diferite nivele de
