[Sunhelp] how to implement ethernet restrictions?

[Wolfgang Engelien]

Hi,

I would like to have communication on one
ethernet adapter (qfe0) only to known ethernet
addresses. Someone who plugs an unknown device
on this switched net should not be able to see
anything other than maybe some broadcasts. Any
ideas?

If it is not possible to have this restriction
only on one ethernet adapter, is possible to
restrict the communication over all to only
known ethernet addresses? Like fixing the ARP
table and discarding all communication attempts
outside that table?

Thanks,
Wolfgang
