Content Filtering; Traffic Redirect - ZyXEL Communications P-870HW-I Series User Manual

P-870HW-I1 User's Guide
TR-069 Compliance
TR-069 is a protocol that defines how your ZyXEL Device can be managed via a management
server such as ZyXEL's Vantage CNM Access. The management server can securely manage
and update configuration changes in ZyXEL Devices.
PPPoE (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your
ISP to use their existing network configuration with newer broadband technologies such as
VDSL. The PPPoE driver on the ZyXEL Device is transparent to the computers on the LAN,
which see only Ethernet and are not aware of PPPoE thus saving you from having to manage
PPPoE clients on individual computers. The ZyXEL Device also includes PPPoE idle time-out
(the PPPoE connection terminates after a period of no traffic that you configure) and PPPoE
Dial-on-Demand (the PPPoE connection is brought up only when an Internet access request is
made).
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet). This can provide security and IP management. Powered by ZyNOS NAT
technology, the ZyXEL Device supports NAT mapping, as well as most popular Internet
multimedia applications, such as NetMeeting, CuSeeMe, IP TV, Quick Time, Real Player
(RSP/RTSP), VoIP SIP ALG, and so on.
Firewall
The ZyXEL Device is a stateful inspection firewall with DoS (Denial of Service) protection.
By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The ZyXEL Device firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

Content Filtering

Content filtering allows you to block access to forbidden Internet web sites, schedule when the
ZyXEL Device should perform the filtering and give trusted LAN IP addresses unfiltered
Internet access.

Traffic Redirect

Traffic redirect forwards WAN traffic to a backup gateway when the ZyXEL Device cannot
connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.
