If the DHCP server option is enabled, you have to be very careful in assigning the IP
addresses of filtered private IP range in order to avoid conflicts because you do not know
which PC in LAN is assigned to which IP address. The easiest and safest way is that the
filtered IP address is assigned to specific PC that is not allowed to access outside resource
such as Internet. You configure the filtered IP address manually to this PC, but it is still in the
same subnet with the router.

can automatically detect and block the DoS (Denial of Service) attack if user enables this function. This
kind of attack is not to achieve the confidential data of this network; instead, it aims to crush specific
equipment or the entire network. If this happens, the users will not be able to access the network
resources. There are few samples of hacker patterns implemented as below.
- IP Spoofing
- Ping of Death (Length > 65535)
- Land Attack (Same source / destination IP address)
- IP with zero length
- Sync flooding
