page 34.
DMZ Setting
On Cisco RV042, RV042G, and RV082, you can configure the Internet/DMZ port
for use as a DMZ (De-Militarized Zone or De-Marcation Zone). Cisco RV016 has a
dedicated DMZ port. A DMZ allows Internet traffic to access specified hosts on
your network, such as FTP servers and web servers. The rest of your network
resources are kept private.
This feature requires that you have a publicly routable IP address for each host on
the DMZ. You can contact your ISP about getting an additional IP address for this
purpose.
NOTE
• Using the DMZ is preferred and is, if practical, a strongly recommended
alternative to using public LAN servers or putting these servers on WAN
ports where they are not protected and not accessible by users on the LAN.
• Each of the servers on the DMZ will need a unique, public Internet IP
address. Your ISP should be able to provide these addresses, as well as
information on setting up public Internet servers. If you plan to use the DMZ
setting, contact your ISP for the static IP information. If your ISP provides
only one static or several dynamic IP addresses, consider using the DMZ
host feature. See Setting Up a DMZ Host, page 43.
Perform the following actions, as needed.
• To configure the DMZ with IPv6 addressing: Click the IPv6 tab. Then
proceed with the other tasks in this section.
Note: The IPv6 tab is available only if Dual-Stack IP is enabled in the IP
Mode section. If you change the IP Mode setting, you must save the settings
before you continue.
• To enable DMZ on the DMZ/Internet port (Cisco RV042, RV042G, and
RV082 only): Check the Enable DMZ box to enable this feature. Then edit
the DMZ settings, as described below. If you want to use the port as a WAN
port instead, uncheck the box, and be sure to configure the WAN settings on
the Dual WAN page. (See Setting Up Dual WAN and Multi-WAN
Connections, page 73.)
