It enables a host computer to access configuration, performance, and other system data that resides in a database on the modem. The host computer is called a management station and the modem is called an SNMP agent. The data that can be accessed via SNMP is stored in a Management Information Database (MIB) on the modem.
Cerberus P 6331-4A UPnP UPnP (Universal Plug and Play) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. An UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly an automatically when it is no longer in use. UPnP broadcasts are only allowed on the LAN.
Cerberus P 6331-4A DDNS The Dynamic Domain Name System allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CUSeeMe, etc.). You can also access your FTP server or Web site on your own computer using a DNS-like address (for instance myhost.dhs.org, where my host is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect.

Cerberus P 6331-4A Troubleshooting If the router is not function properly, first check this session for simple troubleshooting before contacting your Internet service provider (ISP) for support. Using LEDs to Diagnose Problems The LEDs are useful aides for finding possible problem causes. Power LED The PWR LED on the front panel does not light up.: 1. Make sure that the power adaptor is connected to the router and plugged in to an appropriate power source. Use only the supplied power adaptor; 2.
Cerberus P 6331-4A 4. 5. 6. 7. For WAN access, you must configure remote management to allow server access from the WAN (or all); Your computer’s and the router’s IP addresses must be on the same subnet for LAN access; If you changed the router’s LAN IP address, then enter the new one as the URL; Remove any filters in LAN or WAN that block web service. The web Interface does not display properly: 1. Make sure you are using Internet Explorer 5.0 (or compatible) and later versions; 2.
Cerberus P 6331-4A Frequent loss of ADSL line sync (disconnections): 1. The ISP provides the WAN IP address after authenticating you. Authentication may be through the user name and password, the MAC address or the host name; 2. The username and password apply to PPPoE and PPPoA encapsulation only. Make sure that you have entered the correct Service Type, User Name and Password (be sure to use the correct casing). Problems with the Internet Access I cannot access the Internet: 1.
