How Do I Configure My DOCSIS Residential Gateway?
Field Name
Description
Port Triggers
Use this link to configure TCP/UDP port triggers. Port
triggering is similar to port forwarding, but is a
dynamic function. In other words, the ports are not
held open, and the ports close if no outgoing data is
detected on the selected ports for a period of 10
minutes
DMZ Host
(Demilitarized Zone)
Use this link to configure an IP address that is visible
to the wide area network (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
A DMZ is used by a company that wants to host its
own Internet services without sacrificing unauthorized
access to its private network. DMZ allows one IP
address to be unprotected while others remain
protected. The DMZ is located between the Internet
and an internal network's line of defense that is a
combination of firewalls and bastion hosts
Typically, the DMZ contains devices accessible to
Internet traffic, such as Web (HTTP) servers, FTP
servers, SMTP (e-mail) servers, and domain name
system (DNS) servers

Use this link to create, configure, and control Virtual
Private Network (VPN) protocols and manage Internet
Protocol Security (IPsec) VPN tunnels.
