SR804N Cable Modem User Manual Figure 10 Setup configuration Enter the information from the Required Information section as indicated: 1.If your ISP uses DHCP, select “DHCP” for the WAN Connection Type, and enter Host Name and Domain name if required. OR If your ISP uses static IP addressing, select “Static IP” for the WAN Connection Type, and enter the information provided by your ISP for Static IP Address, Static IP Mask, Default Gateway, Primary DNS, and Secondary DNS. 2.
SR804N Cable Modem User Manual Note that communication on the LAN will work regardless of whether the WAN connection provided by the cable modem is up. However, you will not be able to access the Internet until the WAN connection is enabled and has an IP address. Some configurations settings are retrieved only once from non-volatile storage when the CMRG first powers up. One such setting is changing the Static WAN IP address parameters.
SR804N Cable Modem User Manual Figure 12 DHCP configuration This page allows configuration and status of the optional internal DHCP server for the LAN. If you have your own DHCP server servicing the LAN side (or choose to “hardcode” all of your PC‟s IP addresses), you can disable the internal DHCP server by selecting the No radio button. If you do this, make sure the IP address assigned to the CMRG is on the same subnet as the external DHCP server (the subnet mask is always 255.255.255.
SR804N Cable Modem User Manual Figure 13 DHCPv6 configuration This page allows configuration of the internal DhcpV6 server for the LAN. When modifying the System Delegated Prefix, set the System Delegated Prefix first, and press Apply so that the system can calculate its LAN Delegated Prefix. 5.2.4 LAN IPv6 Choose Basic > LAN IPv6 , and the following page appears. Figure 14 LAN IPv6 information This page displays information related to IPv6 on the LAN. 5.2.
SR804N Cable Modem User Manual Figure 15 DDNS setup This page is used to configure DDNS. Dynamic DNS (DDNS) allows a dynamic IP address to be aliased to a static, pre-defined host name so that the host can be easily contacted by other hosts on the internet even if its IP address changes. The CMRG supports a dynamic DNS client compatible with the Dynamic DNS service (http://www.dyndns.com/). To activate the DDNS client: 1. Go to the DynDNS website and create an account for the Dynamic DNS service.
SR804N Cable Modem User Manual Figure 16 Backup In this page, you can save the current CMRG configuration settings to a local PC. You can then later restore these settings if you need restore a particular configuration, or to recover from changes you may have made that have had an undesirable effect. To backup the current configuration, click Backup and follow the prompts. To restore a previous configuration, click Browse and use the navigation window to locate the file. (Usually GatewaySettings.
SR804N Cable Modem User Manual 5.3 Advanced Choose Advanced and the submenus of Advanced are shown as below. Figure 17 Submenus of advanced 5.3.1 Options Choose Advanced > Options to display the following page.
SR804N Cable Modem User Manual Figure 18 Advanced options This page allows you to configure the accessible features. To enable a feature, click the appropriate check box until it is “checked”. When you are satisfied with your selections, click on the Apply button. These features can be modified on the fly without a system reset. “WAN Blocking” prevents the CMRG or the PCs behind it from being visible to the WAN. For instance, pings to the CMRG‟s WAN IP address or the PCs behind it are not returned.
SR804N Cable Modem User Manual “Multicast Enable” allows multicast specific traffic (denoted by a multicast specific address) to be passed to and from the PC‟s on the private network behind the CMRG. “UPnP Enable” enables the UPnP agent in the CMRG. If you are running a CPE application that requires UPnP, check this box. 5.3.2 IP Filtering Choose Advanced > IP Filtering to display the following page.
SR804N Cable Modem User Manual Figure 20 MAC filtering configuration This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN via their MAC address This is useful for the fact that the MAC address of a specific NIC card never changes, unlike its IP address which can be assigned via DHCP server or hard-coded to various addresses over time. 5.3.4 Port Filtering Choose Advanced > Port Filtering to display the following page.
SR804N Cable Modem User Manual Figure 21 Port Filtering configuration This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and ending port range, you may determine what TCP/UDP traffic is allowed out to the WAN on a per-port basis. Note the specified port ranges are blocked for ALL PCs and this setting is not IP address or MAC address specific.
SR804N Cable Modem User Manual If both external and Local/internal port numbers are present, the Local port number is a mandatory field and the external port number is optional. If the external port number is used, the RG will perform a translation from external port number to internal port number. 5.3.6 Port Triggers Choose Advanced > Port Triggers to display the following page.
SR804N Cable Modem User Manual Figure 24 DMZ Host setup DMZ (De-militarized Zone) hosting (also commonly referred to as “Exposed Host”) allows you to specify the “default” recipient of WAN traffic that NAT is unable to translate to a known local PC. This can also be described as a computer or small sub-network that sits between the trusted internal private LAN, and the untrusted public Internet. You may configure one PC to be the DMZ host.
SR804N Cable Modem User Manual Figure 25 RIP Setup RIP (Router Information Protocol) is used in WAN networks to identify and use the best known and quickest route to given destination addresses to help reduce network congestion and delays. NOTE: RIP messaging will only be sent upstream when running in Static IP Addressing mode on the Basic – Setup page. You must enable Static IP Addressing and the set the Wan IP network information! RIP is normally a function that is tightly controlled via the ISP.

SR804N Cable Modem User Manual Figure 27 Basic configuration The “low” setting does not block any services/ports, however it does protect against invalid packets and well known attacks. The “medium” setting will cause the firewall to drop a packet unless it is on a specific port of allowed services, The allowed services are listed on the same page. The “high” setting is similar to “medium”, but allows access to even fewer services. The “off” setting allows all traffic to pass.
SR804N Cable Modem User Manual Figure 28 Local Log The Local Log can send firewall attack reports out in two different ways. Individual emails can be sent out automatically, each time the firewall is under attack, and also a local log is stored within the modem and displayed in table form on the Local Log page.
SR804N Cable Modem User Manual connections, known Internet attack types, and CMRG configuration events can be logged. The SysLog server must be on the same network as the Private LAN behind the CMRG (typically 192.168.0.x). To activate the SysLog monitoring feature, check all desired event types to monitor and enter the last byte of the IP address of the SysLog server.
