Procedure

Navigation

1. Navigate to a device web session for your router.

2. Click the Manage dropdown, then click Routers.

DHCP

Selecting DHCP will have the router automatically configure its IP address, netmask, and default gateway for the WAN interface.

Static

Selecting Static IP will allow you to configure the following networking settings for the router's WAN interface:

  • Primary: Allows you to select what set of configurations the WAN interface will use.
  • WAN IP: Allows you to enter a WAN IP address.
  • Subnet Mask: Allows you to enter the subnet mask of the network the WAN interface is connected to.
  • Default Gateway: Allows you to enter the default gateway the WAN interface is connected to.
  • Primary DNS server: Allows you to enter the primary DNS server the router will use to resolve a hostname.
  • Backup DNS server: Allows you to enter a backup DNS server if the primary is unreachable.
All static WAN IP addresses must be in the same subnet.

PPPoE

Point-to-Point Protocol over Ethernet (PPPoE) is a specification used to authenticate a networking device to an Internet Service Provider (ISP). Selecting PPPoE will allow you to enter the following information:

  • PPP Username: Allows you to enter the username associated with your ISP
  • PPP Password: Allows you to enter the password associated with your ISP
  • VLAN ID: Allows you to enter the VLAN ID associated with your ISP
  • Access Concentrator: Allows you to enter the access concentrator associated with your ISP
  • Service: Allows you to enter the service name associated with your ISP
  • Host-Uniq Tag: Allows you to enter the host-uniq tag associated with the access concentrator and your ISP
Configure PPPoE as directed by your Internet Service Provider, and contact them as necessary to obtain relevant information.

DNS

When selecting DHCP or PPPoE, you can choose one of two DNS options using the DNS Server dropdown:

  • Automatic: The router will automatically obtain and use DNS servers via DHCP
  • Manual: The router will use the DNS servers entered in the Primary DNS server and Backup DNS server fields, as shown in Figure 3

1:1 NAT

1:1 NAT is a feature for static IP configurations that allows you to redirect traffic from a pool of one or more external IP addresses to an internal IP address using Network Address Translation (NAT). This allows you to run multiple services on the same port, such as some VoIP services and web servers.

To configure 1:1 NAT, perform the following steps:

1. Configure at least one set of static IP settings, and click Save Router Settings.

2. Device Name: Enter a name associated with the rule.

3. Incoming IP: Select an incoming external IP address to forward.

4. Destination IP: Enter an internal IP address.

5. Add/Remove: Click Add to add the 1:1 NAT rule. Click Remove to remove an existing rule.
