yes, that's exactly what it means.

uh,uh. things start getting complicated, especially because i missed the 
beginning of the thread. from what i can figure out, your configuration
is the following:
	      (     eth1(
	                    /          \
	                   /            \
	( MICKEY            MINI (

and on goofy your hosts file is
 #file /etc/hosts localhost localhost.domain GOOFY.ORION.DE GOOFY t-online.de t-online  MINI.ORION.DE MINI MICKEY.ORION MICKEY

first: DONT use real (internet) domain names if you ever want to connect
your system to the internet. this will save you a lot of troubles.

- Can all machines ping each other by IP ?(that would mean IP-forwarding

- Who can ping whom by name? thats a matter of name resolution. i noticed
  that you have  MINI.ORION.DE MINI
  maybe thats the source for some of your problems.

- How do the /etc/hosts files of the clients (mickey, mini) look like?
  if you want them to ping each other by name you will have to do one
  of the following:
  + keep correct hosts files on every client. bad idea, esp. if you want
    to attach more clients to your network.
  + serve /etc/hosts by NIS. thats what i would do for a home network.
  + install a DNS server on goofy for your domain. maybe too sophisticated
    for just a few clients - except you want to learn how to run a DNS

What i did not catch at all: why are you serving two clients by two NICS?
would make sense only for an exercise on 'how to configure ipforwarding'
