Hi!
I want to switch from my old Linux (AXP) box to FreeBSD and installed
Release 4.6 on a new PC (Pentium 4).
My goal is to go for a less painful upgrade -- did you ever upgrade
a SuSE installation?
Nearly everything went smooth - even X11.
Unfortunately i have a big problem with my internet connection using
usermode ppp and ISDN.
I have an AVM Fritz PCI v2.0 card (ifpi2 driver).
It sort of works, but i can only send about 30 packages. After that,
the connection is dead.
I tested it with 'ping 62.155.254.208' (the DNS server of my ISP T-Online).
After issuing the command, i have to wait for the dial in, then about
30 packages come through without any problem, after that the output
stops and i see messages like that on the first console:

I assume i made a silly mistake so please give me some advice.
First i thought, some IP packages from previous connections hang around
at T-Online and i have to get rid of them so i used a firewall script.
But the problem is still present.
Please have a look at my configuration files and tell me any strange
entries, too:
