In this example, ether1 is the physical port connecting to customer.
Modify as needed.
/interface bridge filter
add action=drop chain=forward disabled=no \
dst-port=68 in-interface=ether1 \
ip-protocol=udp mac-protocol=ip src-port=67
This would drop a DHCPOFFER packet originating on the ether1 (customer)
side of the bridge. You wouldn't have to have more than this to prevent
a customer's DHCP server from exiting their CPE onto the larger network.
