Action
Specifies the rule – the type of action the router performs:
•
allow
– The router allows the packets to enter the network.
•
deny
– The router denies the packets from entering the net-
work.
Table 29: Forwarding filtering
When you enable the
Enable filtering of locally destined packets
function, the router drops
the 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.
