Field Name Description Options Use this link to enable or disable advanced features on your network IP Address Filtering Use this link to configure IP address filters. These filters prevent designated IP addresses from accessing the Internet MAC Address Filtering Use this link to configure MAC address filters. These filters prevent designated MAC addresses from accessing the Internet Port Filtering Use this link to configure transmission control protocol (TCP) and user datagram protocol (UDP) port filters. These filters prevent a range of TCP/UDP ports from accessing the Internet Port Forwarding Use this link to configure port forwarding for local IP addresses. Port forwarding allows you to run a server on the local area network (LAN) by specifying the mapping of TCP/UDP ports to local PCs or to the IP address of other devices. This is a static setting that holds the ports open at all times
4028315 Rev A 33 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 networks 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. Firewall The following table provides a description of the pages available from within the Firewall section of the Setup page.
