Moin,

Doch nicht ganz Fehlanzeige:

Allerdings dauert das ziemlich lange, bis überhaupt etwas passiert.

telnet www.google.com 80
...nach langer Zeit...
www.google.com:hostname nor servname provided, or not known

Der dazu gehörige tcpdump:

tcpdump -v -n -i tun0
tcpdump: listening on tun0, link-type NULL (BSD loopback), capture size
96 bytes

Was passiert da mit www.google.com.intranet.local.? Wieso kommt da
plötzlich unsere interne domain ins Spiel?

Übrigens bekomme ich mit einem telnet auf eine IP-Adresse (z.B. google)
eine Verbindung!

telnet <ip-adresse> 80
Trying <ip-adresse>
Connected to <ip-adresse>
Escape chracter is '^]'.

Weiß nicht, wieviel oder wie wenig Erfolg das bedeutet.

Aufgefallen sind mir noch die folgenden Meldungen aus der ppp.log:

ppp[740]: tun0: Phase: deflink: HDLC errors -> FCS: 8, ADDR: 0, COMD: 0,
PROTO: 0
ppp[740]: tun0: Phase: deflink: HDLC errors -> FCS: 2, ADDR: 0, COMD: 0,
PROTO: 0

Weiß jemand, was das bedeutet?

Gruß,
Benjamin
