Ipsec Vpn Capability; Packet Filtering - ZyXEL Communications P-335WT User Manual

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 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.
Content Filtering
The Prestige can also block access to web sites containing keywords that you specify. You can
define time periods and days during which content filtering is enabled and include or exclude a
range of users on the LAN from content filtering.

Packet Filtering

The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.
Time and Date
The Prestige allows you to get the current time and date from an external server when you turn
on your Prestige. You can also set the time manually.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices
on the network.
Call Scheduling
Configure call time periods to restrict and allow access for users on remote nodes.
PPPoE
PPPoE facilitates the interaction of a host with an Internet modem to achieve access to high-
speed data networks via a familiar "dial-up networking" user interface.
