Network Access Protection
From the
Administration > Security > Network Access Protection
window, you
can enhance the security of the system and prevent unwanted intrusion. Network
access protection shields the NAS from Internet attacks by automatic IP blocking.
You can define the rules of IP blocking for different services or protocols.
NOTE
If the Security Level is set as High, Network Access Protection will be
disabled since only connections from specified IP addresses are permitted
access.
