Nö, läuft hier schon seit längerem, ab slink oder vorher...

Multilink-PPP muß im Kernel eincompiliert sein.

Die zum Testen evtl. erstmal zur Seite schieben.

Ich poste mal meine modifizierte device.ippp0, in ipppd.ippp0 sollte
als erste Option stehen:

# STANDARD OPTIONS
/dev/ippp0 /dev/ippp1

Dann die Option +mp auskommentieren, das wars mit dieser Datei. Statt
ippp1 kann man natürlich auch eine andere Zahl benutzen, ich glaube,
das hatte ich so mal laufen.

Hier das device.ippp0 zum Vergleichen und Anpassen:
