For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality.

Demilitarized Zone (DMZ) Settings on SPA8000 Analog Telephone Adapter

Objective

The Demilitarized Zone (DMZ) feature puts one network computer, usually one which provides services to users outside of the network and is therefore more vulnerable, in a subnetwork exposed to the Internet. This adds an additional layer of security to the local area network (LAN). The objective of this article is to explain the DMZ settings on the SPA8000 Analog Telephone Adapter.

Applicable Devices

• SPA8000 Analog Telephone Adapter

Software Version

• 6.1.12

Configuration of DMZ

Step 1. Log into the web configuration utility as an administrator or user and choose Advanced > Network > Application. The Application page opens:

Step 2. Choose Yes from the Enable DMZ drop-down list to expose one host to the Internet

Note: Any host whose port is forwarded must have its DHCP client function disabled and should have a new static IP address assigned to it because DHCP may change the IP address.

Step 3. Enter the digits required to complete the host IP address in the DMZ Host IP Address field.

Step 4. Click Submit All Changes to save the settings.
