Policy
. This allows the filtering policy to be specified (
accept
,
drop
or
reject
).
When the filtering policy is
accept
, only packets complying with the established rule
are accepted. When the filtering policy is
drop
, on the other hand, packets
complying with the established rule are dropped. The
reject
filtering policy also
rules out packets complying with the established rule, but unlike drop, when the
packet is ruled out, the appropriate ICMP message is sent to the source address of
the packet.
•
Description.

interface coming from host 10.0.0.5, whose destination is within the IP range

eth0
block configuration will be that shown in the figure.
