Here are my ZyXEL Prestige 660R-61 settings.
Description
ADSL 2+ modem (RJ11). LAN only. IPv4.
Change Settings
1) Unplug modem's cable from the wall.
2) OS X 10.7: System Preferences: Network: Local Area Network
Configure IPv4: Manually
IP Address: 192.168.1.30 (my PC)
Subnet Mask: 255.255.255.0
Router: 192.168.1.1 (ZyXEL modem)
3) Go to: http://192.168.1.1/
Settings
Advanced Setup
LAN (LAN: your local network (LAN) is connected to internet (WAN) through your Prestige. Your LAN may have multiple clients that need to know their IP addresses.)
DHCP: [None] (Use Prestige as your LAN's DHCP server. DHCP is used with DNS. Prestige can work as DHCP server to assign IP addresses to clients.)
Client IP Pool Starting Address: [N/A]
Size of Client IP Pool: [N/A]
Primary DNS Server: [N/A] (If your ISP gives you the DNS server addresses, enter them in the DNS Server fields.)
Secondary DNS Server: [N/A]
Remote DHCP Server: [N/A]
TCIP/IP (TCIP/IP: when changing Prestige settings, you need to define static IP address and subnet mask in your computer to connect to Prestige.)
IP Address: [192.168.1.1] (ZyXEL modem)
IP Subnet Mask: [255.255.255.0]
RIP Direction: [None] (RIP: exchange routing information with other routers.)
RIP Version: [N/A]
Multicast: [None]
WAN
Name: [MyISP]
Mode: [Bridge]
Encapsulation: [RFC 1483] (RFC 1483: ATM network. Other encapsulation methods: PPPoA (authenticated connection, used by DSL carriers). PPPoE (emulate dialup connection, used by telephone companies).)
Multiplex: [LLC] (ATM encapsulation)
Virtual Circuit ID
(Virtual circuit: data is always delivered along the same network path. Virtual circuit is identified by a virtual path identifier (VPI) and virtual channel identifier (VCI) pair.)
VPI: [0]
VCI: [100]
ATM QoS Type: [UBR] (ATM QoS mechanisms: CBR, VBR, ABR, UBR. UBR: traffic is allocated to all remaining transmission capacity.)
Cell Rate
Peak Cell Rate: [0] cell/sec (used with CBR)
Sustain Cell Rate: [0] cell/sec (used with VBR)
Maximum Burst Size: [0] (used with CBR)
NAT
Network Address Translation
(*) None (Disable, because usually done by routers: avoid double NAT. Other options: SUA ("partial" NAT, allow multiple users share the same IP address). Full Feature: "full" NAT.)
Security
(As a home user I have no Telnet/FTP/Web servers that need to be contacted. First four settings are from WAN to LAN, so they can be disabled.)
[x] Telnet
[x] FTP
[x] TFTP
[x] Web
[ ] SNMP
[ ] Ping
Dynamic DNS (DDNS: you can have a static hostname for a dynamic IP address.)
[ ] Active
Service Provider: [www.DynDNS.org]
Host Name:
E-mail Address:
User:
Password:
[ ] Enable Wildcard
Time and Date
(Not needed. ZyXEL doesn't need to act as a time server, so it doesn't need to get time outside my LAN. My computer can contact time servers itself.)
Time Server
Use Protocol when Bootup: [NTP (RFC-1305)]
IP Address or URL: [fi.pool.ntp.org] (not working with 0.fi.pool.ntp.org either)
Time and Date: [(GMT+02:00) Athens, Helsinki, Istanbul, Cairo, Eastern Europe, Israel]
[ ] Daylight Savings (the below two settings are to define the start and end dates of summer time)
Start Date: [1] month [1] day
End Date: [1] month [1] day
[ ] Synchronize system clock with Time Server now
Date
Current Date: [2000] [01 ] [31] (initial value)
New Date (yyyy-mm-dd): [ ] [ ] [ ]
Time
Current Time: [21] [29] [12] (example value)
New Time: [ ] [ ] [ ]
Remote Management
(Change Prestige settings also outside LAN or not.)
Server Type / Access Status / Port / Secured Client IP
Telnet / [LAN Only] / [23] / [0.0.0.0]
FTP / [LAN Only] / [21] / [0.0.0.0]
Web / [LAN Only] / [80] / [0.0.0.0]
UPnP (UPnP: find other UPnP devices on the network. UPnP Traversal automates UPnP through NAT. Should work with Windows Messenger 4.7, which uses UPnP (as does Xbox). Messenger 5.0 and Xbox were still tested during the writing of the Prestige manual.)
[ ] Enable the Universal Plug and Play (UPnP) Service
[ ] Allow users to make configuration changes through UPnP (UPnP devices may configure Prestige, so they can communicate through Prestige. Try to enable this option with the above one, if you are having problems with UPnP.)
(Filtering)
(Manage filter rules also with telnet.)
(System Maintenance Log)
("Time calibration failed": look for this message when having problems with NTP servers.)
("Successful TELNET login": someone has logged on to Prestige.)
(ICMP notes. Type 0, Code 0: Echo reply message. Type 13, Code 0: Timestamp request message.)
