block local traffic

Hi,
I know that this issue was already speak in the forum but i didnt see the solution.
How can i block all my local traffic ? I don’t want that the people that is under the LAN can ping or see each other.

Thanks
Andres

perhaps this could be accomplished in your switch configuration (i.e. each port a separate VLAN … and allow the port the MT is connected to to see the traffic of each switch…)

Additionaly to invader zog post, router ‘ip firewall’ allows to block traffic for clients IP communications, note there is traffic that is not reaching router, it could be treated by switch.

Both are right, but i don´t have a manage switch so im not able to do that on that layer.
