Death, IP Spoofing and so on.
If set as Enabled, then it will shut down outbound ICMP and abnormal
packet responses in connection. If users try to ping the WAN IP from the
external, this will not work because the default value is set as activated in
order to decline the outbound responses.
To enter the device web- based UI by connecting to the remote Internet,
this feature must be activated. In the field of remote browser IP, a valid
external IP address (WAN IP) for the device should be filled in and the
modifiable default control port should be adjusted (the default is set to
80, modifiable).
There are many audio and visual streaming media on the network.
Broadcasting may allow the client end to receive this type of packet
message format. This feature is off by default.
This feature is designed to prevent the intranet from being attacked by
ARP spoofing, causing the connection failure of the PC. This ARP virus
cheat mostly occurs in Internet cafes. When attacked, all the online
computers disconnect immediately or some computers fail to go online.
Activating this feature may prevent the attack by this type of virus.
