DMZ
This router supports one of the physical ports to be congured as a secondary WAN Ethernet port or a dedicated
DMZ port. A DMZ is a sub network that is open to the public but behind the rewall. The DMZ adds an additional
layer of security to the LAN, as specic services/ports that are exposed to the internet on the DMZ do not have
to be exposed on the LAN. It is recommended that hosts that must be exposed to the internet (such as web or
email servers) be placed in the DMZ network.
Firewall rules can be allowed to permit access specic services/ports to the DMZ from both the LAN or WAN. In
the event of an attack to any of the DMZ nodes, the LAN is not necessarily vulnerable as well.
DMZ conguration is identical to the LAN conguration. There are no restrictions on the IP address or subnet
assigned to the DMZ port, other than the fact that it cannot be identical to the IP address given to the LAN
interface of this gateway.
Note: For the DSR-500N and 1000N, in order to congure a DMZ port, the router’s congurable port must be set to
DMZ in the Network > Internet > DMZ Settings page.
Note: For DSR-150N and DSR-250N, enabling DMZ will result in port 8 of the LAN switch being used for a dedicated
DMZ port. The other 7 LAN ports remain unchanged.
