(It is in there isn't it ?). When ppp the fires up it creates its own tun device, taking the next "free" name which is tun1 as tun0 already exists and ppp can't know if it is used by something else. Try removing all references to tun0 from /etc/rc.conf Keep in mind that this is only a guess. Also look at what hides behind PID 212. You can see in th output you provided that tun0 was created by that PID. Hexren
