This manual covers the use of mpd, a multi-link PPP daemon for FreeBSD based on netgraph(4). Mpd is highly configurable and extendable as well as being very fast. It supports many combination of drivers and protocols including asynchronous serial (e.g., modems), synchronous serial, Frame Relay, PPTP, and others. This manual documents mpd version 4.2.2. This version relies on the Netgraph networking system to combine the advantages of user-level configuration and negotiation flexibility with kernel-level speed of data handling. You must be running FreeBSD version 4.x or higher.
