Advanced setup in the modem settings

The advanced setup area of your modem GUI gives you greater control over your modem's operation. These settings are best for tech-savvy folks who understand a bit more than the typical user about modems and networking. 

How to access the Advanced Setup menu

Note:  Your modem settings may appear slightly different from the images below, but the steps will be the same.

Advanced setup menu options

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

Blocking and scheduling options are not available on modems with Secure WiFi.

 

  • Access Scheduler: Set internet access times for a device connected to your network.

  • Service Blocking: Block specific internet services from a device connected to your network.

  • Website Blocking: Block a device from accessing certain websites.

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

WAN settings

WAN Settings: 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 IPv6IPv6 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: 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 configurationCBRAS 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.
Quality of Service (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.

  • Remote Telnet (for older modems only): Remote Telnet enables "Secure Shell" (SSH) access to your router over a WAN connection using the modem's IP address.

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. 

Network Address Translantion (NAT): 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.
