Traffic Redirect - ZyXEL Communications Prestige 792H User Manual

Prestige 792H User's Guide
IPSec VPN Capability
Establish a Virtual Private Network (VPN) to connect with business partners and branch offices using data
encryption and the Internet to provide secure communications without the expense of leased site-to-site
lines. The Prestige's VPN is based on the IPSec standard and is fully interoperable with other IPSec-based
VPN products.
Firewall
The Prestige 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 Prestige firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts,
reports and logs.
IPSec VPN Capability

encryption and the Internet to provide secure communications without the expense of leased site-to-site
lines. The Prestige VPN is based on the IPSec standard and is fully interoperable with other IPSec-based
VPN products.

Traffic Redirect

Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the
Internet, thus acting as an auxiliary if your regular WAN connection fails.
Auxiliary Port
The auxiliary port (or dial backup port) can be used in reserve as a traditional dial-up connection when/if
ever the broadband connection to the WAN port fails. The P792H/HW uses the same port (labeled
CON/AUX) for console management and for an auxiliary WAN backup (push the CON/AUX switch to
CON or AUX).
SNMP (Simple Network Management Protocol – versions 1 and 2)
SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your Prestige supports SNMP agent functionality that allows a manager station to manage
and monitor the Prestige through the network.
SNMP is only available if TCP/IP is configured on your Prestige.
IP Multicast
Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management
Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236);
the Prestige supports both versions 1 and 2.
