Because it told everyone in the 1.0 subnet that it was the route to
the 2.0 subnet - which all the machines should have treated as local
and done arps for.  It should only have advertised itself as the route
to the 4.0 subnet.

The system was (more or less) capable of transferring the traffic
onto the private subnet, but no way could it cope with the traffic
that sat on the main LAN.

That particular LAN was also bridged for non-IP traffic, I identified
over 1000 different MAC addresses on it.
