ZyXEL Communications P-334WT Support Notes page 11

1. WinGate is a software only solution that needs to be installed in a dedicated Windows 95 PC
based server. The total cost and complexity are many times over ATI's product. The Prestige
Internet Access Sharing Router is a plug-n-play internet appliance.
2. WinGate requires all TCP/IP applications such as Netscape Navigator to be reconfigured to have
the dedicated server as a proxy. The Prestige Internet Access Sharing Router does not require
users to reconfigure any software at all.
3. The Prestige Internet Access Sharing Router uses Network Address Translation (NAT) scheme,
which supports all TCP/UDP ports. WinGate only supports limited number of ports, such as http
(80), ftp(21), telnet(23), and pop3(110).
4. WinGate works as a proxy, while the Prestige Internet Access Sharing Router works as a
gateway. The gateway approach is more efficient than the proxy during the processing of TCP/IP
commands. As a result, the Prestige Internet Access Sharing Router achieves 10% to 20% higher
performance than that of software solutions such as WinGate.
5. The Prestige Internet Access Sharing Router uses Solid State Disk technology. There are no
moving parts in the product. It is much more reliable than any hard disk based system, such as the
one for WinGate.
16. What is the difference between the 'Standard' and 'RoadRunner' service?
The US Road Runner
to the outside network. This is apparently implemented in the TAS (Toshiba Authentication System)
with a packet filtering firewall in the upstream direction. Before login, one can send ICMP packets (e.g.,
ping) to the outside Internet, but nearly all other upstream TCP and UDP packets are blocked. The user
can only speak to the local DNS/login server. Downstream packets do not appear to be filtered or
blocked at any time.
While Standard service means the cable services which have no login requirement. Prestige supports
both Road Runner & Standard
17. Is it possible to access a server running behind SUA from the outside Internet? If possible,
how?
Yes, it is possible because Prestige delivers the packet to the local server by looking up to a SUA server
table. Therefore, to make a local server accessible to the outside users, the port number and the inside IP
address of the server must be configured in Menu 15 - SUA Server Setup.
18. What DHCP capability does the Prestige support?
The Prestige supports DHCP client on the WAN port and DHCP server on the LAN port. The Prestige's
DHCP client allows it to get the Internet IP address from ISP automatically. The Prestige's DHCP server
allows it to automatically assign IP and DNS addresses to the clients on the local LAN.
service requires the user to "log in" to the service before it can send any packets
services in menu 4 for connecting to cable ISPs.
