Note: It is protected by super password, ‘1234’ by factory default. 4. How do I update the firmware and configuration file? You can do this if you access the P-660HW-Tx v3 as Administrator. You can upload the firmware and configuration file to Prestige from Web Condigurator, or using FTP or TFTP client software.
Page 7: How Do I Upgrade/Backup The Zynos Firmware By Using Tftp Client Program Via Lan
In case you forget the system password, you can erase the current configuration and restore factory defaults this way: Use the RESET button on the rear panel of P-660HW-Tx v3 to reset the router. After the router is reset, the LAN IP address will be reset to '192.168.1.1', the common user password will be reset to 'user', the Administrator password will be reset to „1234’.

Many-to-One and Server. With SUA, 'visible' servers had to be mapped to different ports, since the servers share only one global IP. The P-660HW-Tx v3 now has Full Feature NAT which supports five types of IP/Port mapping: One to One, Many to One, Many to Many Overload, Many to Many No Overload and Server.
Page 9: Is It Possible To Access A Server Running Behind Sua From The Outside Internet? How Can I Do It
11. Is it possible to access a server running behind SUA from the outside Internet? How can I do it? Yes, it is possible because P-660HW-Tx v3 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.
Page 10: How Many Network Users Can The Sua/Nat Support
The Prestige does not limit the number of the users but the number of the sessions. The P-660HW-Tx v3 supports 2048 sessions that you can use the 'ip nat session' command in CLI to see. You can also use „ip nat hashTable wanif0‟...

You can also check your ISP or the information sheet given by the ISP. Please choose PPPoE as the encapsulation type in the P-660HW-Tx v3 if the ISP uses PPPoE. 8. Why does my provider use PPPoE? PPPoE emulates a familiar Dial-Up connection.
Page 14: When Do I Need Ddns Service
IP address we can use the DDNS service. The DDNS server allows to alias a dynamic IP address to a static hostname. Whenever the ISP assigns you a new IP, the P-660HW-Tx v3 sends this IP to the DDNS server for its updates.
Page 15: Why Do We Perform Traffic Shaping In The P-660Hw-Tx V3
All applications have their own natural bit rate. Large data transactions have a fluctuating natural bit rate. The P-660HW-Tx v3 is able to support variable traffic among different virtual connections. Certain traffic may be discarded if the virtual connection experiences congestion.

2. What makes P-660HW-Tx v3 secure? The P-660HW-Tx v3 is pre-configured to automatically detect and thwart Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND attack, IP Spoofing, etc. It also uses stateful packet inspection to determine if an inbound connection is allowed through the firewall to the private LAN.
Page 21: What Kind Of Firewall Is The P-660Hw-Tx V3

Page 26: Log And Alert
Log and Alert 1. When does the P-660HW-Tx v3 generate the firewall log? The P-660HW-Tx v3 generates the firewall log immediately when the packet matches a firewall rule. The log for Default Firewall Policy (LAN to WAN, WAN to LAN, WAN to WAN) is generated automatically with factory default setting, but you can change it in Web Configurator.
Page 27: When Does The P-660Hw-Tx V3 Generate The Firewall Alert
5. What is the difference between the log and alert? A log entry is just added to the log inside the P-660HW-Tx v3 and e-mailed together with all other log entries at the scheduled time as configured. An alert is e-mailed immediately after an attacked is detected.

In this case, we use P-660HW-Tx v3 which works as an ADSL bridge modem to connect to the ISP. The ISP will generally give one Internet account and limit only one computer to access the Internet.

Page 45 Also, since you need to specify the IP address of a server behind the P-660HW-Tx v3, a server must have a fixed IP address and not be a DHCP client whose IP address potentially changes each time P-660HW-Tx v3 is powered on.

Page 63: Using The Dynamic Dns (Ddns)
Without DDNS, we always tell the users to use the WAN IP of the P-660HW-Tx v3 to access the internal server. It is inconvenient for the users if this IP is dynamic. With DDNS supported by the P-660HW-Tx v3, you apply a DNS name (e.g., www.zyxel.com.tw) for your server (e.g., Web server) from a DDNS server.
Page 64 P-660HW-Tx v3 Series Support Notes When the ISP assigns the P-660HW-Tx v3 a new IP, the P-660HW-Tx v3 must inform the DDNS server the change of this IP so that the server can update its IP-to-DNS entry. Once the IP-to-DNS table in the DDNS server is updated, the DNS name for your web server (i.e., www.zyxel.com.tw) is still usable.
Page 65: Network Management Using Snmp
 ZyXEL SNMP Implementation ZyXEL currently includes SNMP support in some P-660HW-Tx v3 routers. It is implemented based on the SNMPv1, so it will be able to comm unicate with SNMPv1 NMSs. Further, users can also add ZyXEL's private MIB in the NMS to monitor and control additional system variables.

Page 68: Using Syslog
In a typical environment, a LAN router is required to connect two local networks. The P-660HW-Tx v3 can connect three local networks to the ISP or a remote node, we call this function as 'IP Alias'. In this case, an internal router is not required.
Page 69 'IP Alias 1' and 'IP Alias 2' can be configured in Network -> LAN -> IP Alias. There are three internal virtual LAN interfaces for the P-660HW-Tx v3 to route the packets from/to the three networks correctly. They are enif0 for the major network, enif0:0 for the IP alias 1 and enif0:1 for the IP alias 2.

This will create the Setup first route in the enif0 interface.
