Answer #2
Wow, this is dated from Apr/08/2012. Here is a fix that might work use bridge filtering:
Bridge Filters
-Accept Input of DHCP requests
-Accept Output of DHCP responses
-Drop forwarding of all DHCP packets
Basic Firewall Port flooding setttings:

add chain=input connection-state=established comment=”Accept established connections”
add chain=input connection-state=related comment=”Accept related connections”
add chain=input connection-state=invalid action=drop comment=”Drop invalid connections”
add chain=input protocol=udp action=accept comment=”UDP” disabled=no
add chain=forward connection-state=invalid action=drop comment=”drop invalid connections”
add chain=input protocol=icmp limit=50/5s,2 comment=”Allow limited pings”
add chain=input protocol=icmp action=drop comment=”Drop excess pings”
Also if you can enable switchport port-security set Maximum MAC Addresses to 1, this is what we have to do for Cisco so I would assume there would be a similar rule for your router just grab the manual.
