Check your IPchains. Most likely there is a rule that tells the hosts to
send redirects.
I'm no expert, but I believe you need to multihome the linux box on each
subnet.
Also, your configuration does not technically meet the specification for a
permenant way of doing things. Ideally you would divide your ethernet into
different subnets and then route between them.
