Table 32: Forwarding filtering
When you enable the Enable filtering of locally destined packets function, the router drops
receives packets requesting an unsupported service. The packet is dropped automatically
without any information.
As a protection against DoS attacks, the Enable protection against DoS attacks limits the
number of allowed connections per second to five. The DoS attack floods the target system
with meaningless requirements.
