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

Use this link to configure an IP address that is

(Demilitarized Zone)

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

 

 

VPN Termination

Use this link to create, configure, and control

 

Virtual Private Network (VPN) protocols and

 

manage Internet Protocol Security (IPsec) VPN

 

tunnels.
