Chapter 1 Getting to Know Your Device

Universal Plug and Play (UPnP) 
Using the standard TCP/IP protocol, the ZyXEL device and other UPnP-enabled devices can 
dynamically join a network, obtain an IP address and convey its capabilities to other devices 
on the network.
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.
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 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. 
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of 
data from a remote client to a private server, creating a Virtual Private Network (VPN) using a 
TCP/IP-based network. PPTP supports on-demand, multi-protocol and virtual private 
networking over public networks, such as the Internet. Use PPTP to connect to a broadband 
modem to achieve access to high-speed data networks via a familiar "dial-up networking" user 
interface. 
Network Address Translation (NAT) 
NAT (Network Address Translation - NAT, RFC 1631) allows the translations of multiple IP 
addresses used within one network to different IP addresses known within another network. 
NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC, 
RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these 
applications. 
Traffic Redirect
Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the ZyXEL 
device cannot connect to the Internet, thus acting as an auxiliary backup when your regular 
WAN connection fails.
