I see in your logfiles: Jul 3 09:13:46 ozlerplastik ppp[14071]: tun0: Phase: deflink: HDLC errors -> +FCS: 3, ADDR: 0, COMD: 0, PROTO: 0 Jul 3 09:57:43 ozlerplastik ppp[14071]: tun0: Phase: deflink: Carrier lost Jul 3 09:57:43 ozlerplastik ppp[14071]: tun0: CCP: deflink: State change +Stopped --> Closed Jul 3 09:57:43 ozlerplastik ppp[14071]: tun0: CCP: deflink: State change Closed +--> Initial Jul 3 09:57:43 ozlerplastik ppp[14071]: tun0: LCP: deflink: LayerDown This is the reason why your pppd drops, it sees FCS errors (Frame Count Sequence) on the HDLC part of the connection. This means that frames sent into your connection are not arriving at the same order you (or the remote end) sent them in. You may want to investigate why this happens, and if this problem is known with your ISP. Otherwise, I haven't seen it before, so I don't have a 'one-size-fits-all' solution for you :/ HTH&HAND, -- Nils Vogels PGP:0xC26BD15F Available on keyservers.
