Hi,

I set up an isdn card in my freebsd-box. I can connect to my provider, ping,
traceroute, resolve names, or work on remote hosts using ssh.
But I can't do anything else e.g. cvsup or even view webpages!
It seems, that my PC doesn't care about the sequence numbers and always
sends back an "ack 1". So I got the latest stable tonight, but nothing changed.
Below is a log of tcpdump when I tried to get a www-page.

Thanks,
JAN

P.S.: The hardware is not broken - at least it works with fli4l.
