Welcome to the ACCEL-PPP Open Source Project

ACCEL-PPP is a high performance VPN server application for linux.
Since version 1.8 it is also IPoE server.
Its goal is aggregation of various popular VPN techniques to a single application.
There are many open source projects which provides VPN services,
but they are specialized to a specific VPN technique: only PPPoE, only PPtP, only L2TP.
And you have to learn, configure and manage each one separately to build multi-service VPN server.
With ACCEL-PPTP you have all-in-one with single configuration, single management, single monitoring.
