Table 91 – Special AP Rule Configuration
3.5.4 DMZ & Pass Through
DMZ (De Militarized Zone) Host is a host that is exposed to the Internet but still within the protection of the router firewall.
The function allows a computer to execute two-way communication for Internet games, Video conferencing, Internet
telephony and other special applications. In some cases when a specific application is blocked by the NAT mechanism, you
can indicate that LAN computer as a DMZ host to solve this problem.
The DMZ function allows you to ask the router to pass through all normal packets to the DMZ host behind the NAT router
only when these packets are not expected to be received by applications on the router or by other client hosts in the
Intranet. Activate the feature and specify the DMZ host with a host in the Intranet when needed.
