Cisco Systems DPC/EPC2325 DOCSIS Configuring the DMZ Host, Setup Advanced Settings DMZ Host

How Do I Configure My DOCSIS Residential Gateway?

Configuring the DMZ Host

Use the Setup Advanced Settings - DMZ Host page to configure an IP address that is visible to the WAN. DMZ hosting is commonly referred to as “exposed host,” and allows you to specify the “default” recipient of WAN traffic that Network Address Translation (NAT) is unable to translate to a known local PC. DMZ allows one IP address to be unprotected while others remain protected.

Note: If you are not familiar with the advanced settings detailed in this section, contact your service provider before you attempt to change any of the residential gateway default advanced DMZ host settings.

Click DMZ Host in the Advanced Settings section of the Setup page to access the Setup Advanced Settings - DMZ Host page.

Setup Advanced Settings - DMZ Host Page

The following illustration is an example of the Setup Advanced Settings - DMZ Host page.

Setup Advanced Settings - DMZ Host Page Description

Use this link to place a Private LAN IP device, for example, an FTP, Mail, or webserver directly on the Internet (bypassing the firewall). You set the server with a fixed IP address as a DMZ Host by entering its IP address in the DMZ Address field. Make sure the IP address used is not in the range of addresses delivered by the built- in DHCP server. After setting up a DMZ Host, all ports on this device are open to the Internet. You may configure only one PC to be the DMZ host. DMZ is generally used for PCs running “problem” applications that use random port numbers and do not function correctly with the specific port triggers or port forwarding setups described earlier in this guide. After entering a DMZ Address, click Apply to apply and save your new DMZ Host setting.
