4.2.1.8 Options
1.
Stealth Mode:
Enable this feature, this device will not respond to port scans
from the WAN so that makes it less susceptible to discovery and attacks
on the Internet
.
2.
SPI:
When this feature is enabled, the router will record the outgoing
packet information pass through the router like IP address, port address,
ACK, SEQ number and so on. And the router will check every incoming packet
to detect if this packet is valid.
3.
Discard PING from WAN:
If this feature is enabled, this gateway won’t reply
any ICMP request packet from WAN side. It means any remote host can’t get
response when “ping” to this gateway. “Ping” is a useful command that we
use to detect if a certain host is alive or not. But it also let hacker know
about this. Therefore, many Internet servers will be set to ignore IGMP
request.
