Allowing all Applications (DMZplus)
DMZplus is a special firewall mode that is used for hosting applications if you cannot get an application to
work properly using the “Allow individual application(s)” option. When in DMZplus mode, the designated
computer:
Shares your gateway’s IP address (Router Address).
Appears as if it is directly connected to the Internet.
Has all of the unassigned TCP and UDP ports opened and pointed to it.
Can receive unsolicited network traffic from the Internet.
Although the computer in DMZplus mode appears to Internet users as though it is directly connected to the
Internet, it is still protected by your system firewall. All traffic is inspected by the firewall’s Stateful Packet
Inspection engine and all known hacker attacks continue to be blocked.
Because all filtered traffic is forwarded to the designated computer, you should use DMZplus mode with
caution. A computer in DMZplus mode is less secure because all available ports are open and all incoming
Internet traffic is directed to this computer.

packet length.
Medium. Occurs when a medium-level threat is detected,
such as an invalid IP fragment offset.
High. Occurs when an attack is launched against the
network (for example, a SYN Flood).
