This would be the first issue, I guess. What exactly does IP
forwarding help to do?
Other helpful users pointed me to have a look at "bridging". Are both
closely related?

Can't really imagine this because MICKEY (win95) has these settings:
This exactly pertubes me because W95 does only seem to support
NT-domanes. Which entries would you suggest on the W95 mashine after
changing "DE" to "HOME_NET"?

The only mashines that cannot ping each other by IP are MICKEY<->MINI,
hence the two out of the two different subnets.
But this relates I guess to ipforwarding you mentioned - could you
help me on this issue?

Rather no  :^)

I was just trying to spare a switch, actually nothing more. But
thinking it again over, yes - it might help me to understand or more
less get a "feeling" of networks.
