Most configuration items may be changed on the fly without a reboot. 5.2.2 DHCP Choose Basic > DHCP, and the following page appears. Figure 10 DHCP configuration This page allows configuration and status of the optional internal DHCP server for the LAN.
SR808ac Cable Modem User Manual 5.2.3 DDNS Choose Basic > DDNS , and the following page appears. Figure 11 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.
SR808ac Cable Modem User Manual 5.2.4 Backup Choose Basic > Backup, and the following page appears. Figure 12 Backup setup In this page, you can save the current CMRG configuration settings to a local PC.

To backup the current configuration, click Backup and follow the prompts.
SR808ac Cable Modem User Manual 5.3 Advanced Choose Advanced and the submenus of Advanced are shown as below: Figure 13 Submenus of advanced 5.3.1 Options Choose Advanced > Options to display the following page.
SR808ac Cable Modem User Manual Figure 14 Options configuration 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.
SR808ac Cable Modem User Manual “ Remote Configuration Management” allows the CMRG to be administered (configured) from the WAN via surfing to the WAN IP address on port 8080 of the CMRG from anywhere on the Internet (e.g. at the browser URL window enter http://WanIPAddress:8080/ to access the CMRG remotely). “ 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.
SR808ac Cable Modem User Manual also check the “enable” box and click apply. The enable box allows you to store filter settings commonly used but not have them active. 5.3.3 MAC Filtering Choose Advanced > MAC Filtering to display the following page.
SR808ac Cable Modem User Manual Figure 17 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.
SR808ac Cable Modem User Manual Figure 18 Forwarding This allows for incoming requests on specific port numbers to reach web servers, FTP servers, mail servers, etc. so they can be accessible from the public internet. A table of commonly used port numbers is also provided.
SR808ac Cable Modem User Manual Figure 19 Port Triggers Port Triggers are similar to Port Forwarding except that they are not static ports held open all the time. When the CMRG detects outgoing data on a specific IP port number set in the “Trigger Range”, the resulting ports set in the “Target Range” are opened for incoming (or sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected on the “Trigger Range” ports for 10 minutes, the “Target Range” ports will close.
SR808ac Cable Modem User Manual 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.
SR808ac Cable Modem User Manual 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.

SR808ac Cable Modem User Manual 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.
SR808ac Cable Modem User Manual CPE’s can be prevented or permitted to access the Internet with entries in this webpage. Filter criteria is the mac address of the CPE and what types of packets that will be dropped. ToD filtering is accomplished on this page also. An Ethernet mac address of all 0’s will apply to all CPE’s. A start and end port of 0 will apply to all ports. 5.4.3 Local Log Choose Firewall > Local Log to display the following page.
