Enumeration
enabled : If an IP packet could not be delivered/forwarded
to destination due to routing errors (e.g. no
matching route exists, interface down/blocked),
the packet is discarded and the system sends an
ICMP 'Destination-Unreachable/Host' message
back to the originator of the packet.
This is the default behavior of the system.
(see ipIcmpDestUnreachHostTcp also)
disabled: If an IP packet could not be delivered/forwarded
to destination due to routing errors (e.g. no
matching route exists, interface down/blocked),
the packet is silently discarded.
ICMP 'Destination-Unreachable/Host' messages
should be disabled with care (only if really
necessary).
The functionality of the virtual REFUSE-Interface
is NOT affected by this parameter - the system
will continue to send ICMP 'Dest-Unreachable/Host'
messages for all packets explicity routed to
this Interface (ifIndex 0).
The functionality of ipExtIfNatSilentDeny=disabled
is NOT affected by this parameter - the system
will continue to send ICMP 'Dest-Unreachable/Host'
messages for incoming IP-Packets that does not
pass the NAT barrier of NAT-enabled Interfaces.
