CBV3843Z4S Cable Modem User’s Manual 8 4.2 Status The Status page shows hardware and software information about the CBV3843Z4S that may be useful to your cable service provider. 4.2.1 Software Status The Software page shows how long the CBV3843Z4S has operated since last being powered up, and some key information the CBV3843Z4S received during the initialization process with your cable service provider. If Network Access shows “Allowed,” then your cable service provider has configured the CBV3843Z4S to have Internet connectivity. If Network Access shows otherwise, you may not have Internet access, and please contact your cable service provider for assistance. 4.3 Basic The Basic page contains the basic features of CBV3843Z4S including Setup, DHCP and Backup 4.3.1 DHCP The DHCP page allows you to activate/deactivate the DHCP server function of the CBV3843Z4S , and, if the DHCP server is activated, to see DHCP leases it has provided.
CBV3843Z4S Cable Modem User’s Manual 9 With this function activated, your cable service provider’s DHCP server provides one IP address for the CBV3843Z4S , and the CBV3843Z4S ’s DHCP server provides IP addresses, starting at the address you set in Starting Local Address field, to your PCs. A DHCP server leases an IP address with an expiration time. To set the maximum number of PCs to which the CBV3843Z4S will issue IP addresses, enter it in the Number of CPEs box and then click Apply. (CPE is another term sometimes used for PC.) The table on the bottom of this page shows the information of DHCP clients including the IP and MAC addresses of each PC. Since MAC addresses are unique and permanently fixed into hardware, you can identify any PC listed by its MAC address. The CBV38Z4C provides leases for 3600 seconds (default), and has an automatic renewal mechanism that will keep extending a lease as long as the associated PC remains active. You can cancel an IP address lease by selecting it in the DHCP Client Lease Info list and then clicking the Force Available button. If you do this, you may have to perform a DHCP Renew on that PC, so it can obtain a new lease. 4.4 Advanced The Advanced page allows you to enable/disable some advanced features of the CBV3843Z4S . 4.4.1 Options The Options page allows you to enable/disable some advanced features supported by CBV3843Z4S .
CBV3843Z4S Cable Modem User’s Manual 10 Check the option you want to use and click Apply button to enable the function(s).  WAN Blocking: To prevent others on the WAN side from being able to ping your CBV3843Z4S . With WAN Blocking on, your CBV3843Z4S will not respond to pings it receives, effectively “hiding” your gateway.  Ipsec PassThrough: To enable IpSec type packets to pass through between WAN and LAN.  PPTP PassThrough: To enable PPTP type packets to pass through between WAN and LAN.  Remote Config Management: To make the Web Management pages of your CBV3843Z4S accessible from the WAN side. Page access is limited to only those who know the CBV3843Z4S access password you set in the Status--Security page. When accessing the CBV3843Z4S from a remote location, you must use HTTP port 8080 and your IP address. This is the "WAN IP address" that appears at the Basic--Setup page. For example, if this IP address were 211.20.15.28, you would navigate to http:// 211.20.15.28:8080 to reach the CBV3843Z4S ’s Web Management page from a remote location.  Multicast Enable: To enable multicast traffic to pass through between WAN and LAN. You may need to enable this to see some types of broadcast streaming and content on the Internet, such as webcasting of a popular live event.  UPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices in the home, office, and everywhere in between. 4.4.2 IP Filtering The IP Filtering page enables you to enter the IP address ranges of PCs on your LAN that you don’t permit to have outbound access ability to the WAN.
CBV3843Z4S Cable Modem User’s Manual 11These PCs can still communicate with each other on your LAN, but packets they originate to WAN addresses are blocked by the CBV3843Z4S . To enable IP Filtering feature of CBV3843Z4S , check the Enable box and click Apply button. 4.4.3 MAC Filtering The MAC Filtering page enables you to enter the MAC address of specific PCs on your LAN that you don’t permit to have outbound access ability to the WAN. These PCs can still communicate with each other through the CBV3843Z4S , but packets they send to WAN addresses are blocked. To enable MAC filtering feature of CBV3843Z4S , enter the MAC address of the LAN device and click Apply button.
CBV3843Z4S Cable Modem User’s Manual 12 4.4.4 Port Filtering The Port Filtering page allows you to enter ranges of destination ports (applications) that you don’t want your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked. For example, you could block access to worldwide web browsing (HTTP port 80) but still allow email service (SMTP port 25 and POP3 port 110). To enable port filtering, enter the Start port and End port for each range. Then select its protocol form the drop-down list and check the Enable box, and click Apply button. To block only one port, set both Start and End ports the same. 4.4.5 Forwarding For communications between LAN and WAN, the CBV3843Z4S normally only allows you to originate an IP connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the destination port (application) matches one you specify. The Forwarding page allows you to specify up to 10 rules.
CBV3843Z4S Cable Modem User’s Manual 13 Using the Port Forwarding page, you can provide local services (web servers, FTP servers, mail servers, etc) for people on the Internet or play Internet games. A table of commonly used port numbers is also provided. 4.4.6 Port Triggers The Port Triggers page allows you to configure dynamic triggers to specific devices on the LAN. This allows for special applications that require specific port numbers with bi-directional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messenging program features may require these special settings. Port Triggering is an elegant mechanism that does the forwarding for you, each time you play the game. You can specify up to 10 port ranges on which to trigger.
CBV3843Z4S Cable Modem User’s Manual 14 4.4.7 DMZ Host The DMZ page allows you to configure a specific network device to be exposed or visible directly to the WAN (public Internet). Setting a host on your local network as demilitarized zone (DMZ) forwards any network traffic that is not redirected to another host via the port forwarding feature to the IP address of the host (PC). This designates one PC on your LAN that should be left accessible to all PCs from the WAN side for all ports. For example, if you locate a HTTP server on this machine, anyone will be able to access that HTTP server by using your CBV3843Z4S ’s IP address as the destination. This may be used when problem applications do not work with port triggers. The setting of “0” indicates NO DMZ PC.
CBV3843Z4S Cable Modem User’s Manual 154.5 Firewall The CBV3843Z4S provides built-in firewall functions, enabling you to protect the system against denial of service (DoS) attacks and other unwelcome or malicious accesses to your LAN. 4.5.1 Local Log The Local Log page allows you to configure the firewall event log reported via email alert, and these attack records are also visible in the table on the bottom of this page.
