@lindie

ich habe so das gefühl, das du nicht wirklich weißt, was du da machst.

icmp - internet control & messaging protocol = ungefährlich

ein broadcast an dhcp geht auch nicht an die von dir genannte subnetmask. ein broadcast vom client an dhcp ist ebenfalls völlig ungefährlich.

broadcasts gehen in aller regel nicht über router.

vielleicht solltest du dir eine firewall aussuchen, die mit weniger sinnlosen meldungsmüll daherkommt?
