Advanced modem setup options

Then, select a menu option from the left sidebar. The full menu of options is listed below, with links to find step-by-step instructions for each setting.

Blocking/Filtering

• Access Scheduler: Allows you to select a device connected to your network and set Internet access rules.
  
• Service Blocking: Allows you to select a device connected to your network and block specific Internet services.
  
• Website Blocking: Allows you to select a device connected to your network and block that device from accessing certain websites.

Broadband Settings: Allows you to change the connection parameters to your service provider. These settings should not be changed unless instructed by your ISP. 

WAN Settings

• WAN Settings: Allows you to change the protocol and addressing type required by your ISP for Internet access. These settings should not be changed unless instructed by your ISP.  
  
• Turn on IPv6: IPv6 is an upgrade of IPv4, the protocol that the internet runs on. 
• Dynamic DNS: Associates the WAN IP address of your router with a hostname. 

LAN Settings

• DHCP Settings: Allows you to edit the DHCP settings that define the LAN addressing parameters for your modem to allocate IP addresses to LAN devices.
  
• DHCP Reservations: Leases a permanent DHCP allocated address to a client.
  
• DNS Host Mapping: Creates a static hostname for the specified IP address in the DSL router. WAN and LAN IP addresses are supported.
  
• LAN Subnets: Your modem can support multiple LAN subnet settings. Use the DHCP Settings page to configure the default IPv4 subnet.
  
• CBRAS configuration: CBRAS is a specialized CenturyLink remote access server that allows multiple sources of internet traffic (cable, DSL or broadband wireless) to converge in a single network. 

QoS: Prioritizes traffic types (such as VoIP) before standard data traffic. Traffic shaping your network with QoS can increase application performance and prevent your network from becoming overloaded.

Remote Management

• Remote GUI: Enables access to the router from a WAN connection. To access your modem remotely you will need to use https:// followed by the modem WAN IP address. You can manage the Administrator Username and Password for the modem GUI here.
  
• Remote Console: Enables telnet or SSH access to the router from a WAN connection using the WAN IP address of the modem.

Routing

• Dynamic Routing: Used if a gateway is set up behind the modem.
  
• Static Routing: Adds routers manually to the routing table. If a change or a failure occurs between two statically defined nodes, traffic will not be rerouted and must wait for the failure to be resolved by the administrator.

Security

• Administrator Password: Prevents outsiders from accessing the firmware settings of the modem. After creating a username and password, you will need to enter them every time you access the modem firmware GUI located at http://192.168.0.1.
  
• Application Forwarding: Forwards ports to the selected LAN device by application name.
  
• Port Forwarding: Allows you to enter ports or port ranges to forward Internet applications to a LAN device.
  
• DMZ Hosting: Enables a LAN device to use the modem WAN IP address as its own. DMZ places the LAN device outside the firewall.
• IPv4 Firewall: Activating the firewall is optional. When the firewall is activated, security is enhanced, but some network functionality will be lost.
  
• IPv6 Firewall: Activating the firewall is optional. When the firewall is activated, security is enhanced, but some network functionality will be lost. 
• NAT (Network address translation): Turning off NAT will open your Broadband Modem to outside intrusion, creating a security risk. These settings should not be changed unless instructed by your ISP.
• UPnP: Simplifies the connection and implementation of devices to your network.
  
• SIP ALG: Enables or disables the ability to pass SIP sessions to the LAN.
