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: Select what set of configurations the WAN interface will use.
  • WAN IP: Enter a WAN IP address.
  • Subnet Mask: Enter the subnet mask of the network used by the WAN interface .
  • Default Gateway: Enter the default gateway used by the WAN interface.
  • Primary DNS server: Enter the primary DNS server the router will use to resolve a hostname.
  • Backup DNS server: 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: Enter the username associated with your ISP
  • PPP Password: Enter the password associated with your ISP
  • VLAN ID: Enter the VLAN ID associated with your ISP (requires router firmware 1.1.0 or higher)
  • Access Concentrator: Enter the access concentrator associated with your ISP
  • Service: Enter the service name associated with your ISP
  • Host-Uniq Tag: Enter the host-uniq tag related to 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 feature 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.
