PPTP (remote access) Using the Point-to-Point Tunneling Protocol (PPTP), you can provide connections to your network through private tunnels over the internet. The protocol itself does not describe encryption or authentication features.

The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP has been made obsolete by Layer 2 Tunneling Protocol (L2TP), IPSec and OpenVPN, but its still commonly used and natively supported by a lage scale of routers and clients. Mar 04, 2018 · and running. If you are browsing the internet from your mobile phone or tablet, PPTP is the VPN protocol for you. PPTP, or Point-To-Point Tunneling Protocol sends packets via a GRE tunnel by using PPP. Sent packets are both encrypted at 128-bit strength and compressed via the MPPE algorithm. PPTP, just like OpenVPN is also able to work with DD-WRT. How-to Allow VPN (PPTP) Connections for Mikrotik VPN Server.

We have to give a username and password to users to connect to PPTP VPN. Enter the Users tab and then click “+” button to add new user. Create A Rule To Allow Firewall. (PPTP) In the firewall, when users connect to PPTP vpn in order to be able to use the internet, we have to create a rule to allow users to use internet. Many routers have the option PPTP / L2TP pass-through. Enable this option to connect via PPTP, L2TP or IKEv2 VPN. If your router doesn’t have this option, you need to open the ports manually.
