Is it not true that a single packet (i.e., a packet with an
appropriately spoofed source-IP such that it will make it through
the filter) can cause problems? Or is two-way conversation between
the router and the attacker required in order to exploit the
If a single packet is all that's required then a simple source-IP
based filter in front of the routing engine isn't enough to protect
yourself in this case.
