Robust Security Features
Your Prestige supports CHAP (Challenge Handshake Authentication Protocol), PAP (Password Authentication
Protocol) and RADIUS (Remote Authentication Dial in User Service). In addition, the SMT is password protected.
You can also configure the LAN, WAN filters to block unwanted incoming and outgoing packets.
Internet Access Sharing
The Prestige 1600 primary support Single User Account (SUA)/Network Address Translation (NAT) which enables
multiple subscribers to access the Internet using a single IP address. The ZyXEL Network Operating System
(ZyNOS) implementation of SUA/NAT allows NetMeeting, CuSeeMe, ICQ and other multimedia application
traffic behind NAT on the client side.
Note that P1600 secondary machine does not support SUA/NAT; only the P1600 primary does on the WAN port.
For a P1600 standalone NAT/SUA is supported over LAN when the Ethernet port is connected to a broadband
modem.
Remote Software Upgrades
The Prestige 1600 uses FLASH memory technology that enables software upgrades without opening the units. The
P1600 can be upgraded via the console port, locally and remotely, as well as via FTP and TFTP.
