Firewall
Your device has 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 
firewall supports TCP/UDP inspection, DoS detection and prevention, real 
time alerts, reports and logs.
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 ZyXEL 
Device VPN is based on the IPSec standard and is  interoperable with other 
IPSec-based VPN products. 
The ZyXEL Device supports up to two simultaneous IPSec connections.
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).
Content Filtering
Content filtering allows you to block access to Internet web sites that contain 
key words (that you specify) in the URL. You can also schedule when to 
perform the filtering and give trusted LAN IP addresses unfiltered Internet 
access.
Universal Plug and Play 
(UPnP)
Your device and other UPnP enabled devices can use the standard TCP/IP 
protocol to dynamically join a network, obtain an IP address and convey 
their capabilities to each other.
PPPoE Support 
(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 ADSL. The PPPoE driver on 
your 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.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a 
dynamic IP address, allowing the host to be more easily accessible from 
various locations on the Internet. You must register for this service with a 
Dynamic DNS service provider.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows the individual clients 
(computers) to obtain the TCP/IP configuration at start-up from a centralized 
DHCP server. Your device has built-in DHCP server capability enabled by 
default. It can assign IP addresses, an IP default gateway and DNS servers 
to DHCP clients. Your device can also act as a surrogate DHCP server 
(DHCP Relay) where it relays IP address assignment from the actual real 
DHCP server to the clients.
IP Alias
IP alias allows you to partition a physical network into logical networks over 
the same Ethernet interface. Your device supports three logical LAN 
interfaces via its single physical Ethernet interface with the your device itself 
as the gateway for each LAN network.
Packet Filters
Your device’s packet filtering function allows added network security and 
management.
