Indeed, both my desktop and my laptop currently contain an ethernet-card
which I connect to my DSL-modem in order to access the net. I want to
connect these two ethernet cards with each other using the cross-over
cable.

I assume you are experiencing some delays on this list, I posted my
/etc/network/interfaces* files a couple of minutes ago.

Thanks its reassuring to see the same solution posted by two different
persons!

At the moment /etc/network/interfaces contains an entry like:
iface eth0 inet dhcp
Will I have to switch between this line and the lines you suggested (and
issue the restart command you mentioned) or can I use my PPPoE
configuration with the above lines as well?

So you would suggest the following /etc/network/interfaces:
auto lo eth0
iface lo inet loopback
iface eth0-lan inet static
192.168.3.1
255.255.255.0
iface eth0-wan inet dhcp

Can you tell me if this would require additional changes to my PPPoE
config?
I can't seem to find how pppd starts the connection. (I mean I can't
figure out wheter or not it calls ifup.)
