Port Triggering
Some applications require that specific ports in the firewall of the device are
open for the remote parties to access. Application rules dynamically open the
firewall ports when an application on the LAN initiates a TCP/UDP connection to
a remote party using the trigger ports. The device allows the remote party from
the WAN side to establish new connections back to the application on the LAN
side using the firewall ports. A maximum of 32 entries can be configured.

DMZ
Since some applications are not compatible with NAT, the device supports the
use of a DMZ IP address for a single host on the LAN. This IP address is not
protected by NAT and it is visible to agents on the Internet with the correct type
of software. Note that any client PC in the DMZ is exposed to various types of
security risks. If you use the DMZ, take measures (such as client-based virus
protection) to protect the remaining client PCs on your LAN from possible
contamination through DMZ.
