Connection Type

This setting specifies the utilization of the WAN connection.

Always-on

results in the WAN connection being used whenever it is available. If

Backup

Priority

and a priority group are selected, the WAN connection is treated as a backup

connection and is used only in the absence of available always-on WAN connection(s) and

higher priority backup connection(s).

The default and recommended connection type is

Always-on

.

Reply to ICMP Ping

If this field is disabled, the WAN connection will not respond to ICMP ping requests. By

default, this setting is

enabled

.

Upload Bandwidth

This setting specifies the data bandwidth in the outbound direction from the LAN through

the WAN interface. This value is provided by your ISP and should reflect the actual speed

of the WAN.

This value is referenced when default weight is chosen for outbound traffic and traffic

prioritization. Setting the correct value here can result in effective traffic prioritization and

efficient use of upload bandwidth.

Download

Bandwidth

This setting specifies the data bandwidth in the inbound direction from the WAN interface

to the LAN. This value is provided by your ISP and should reflect the actual speed of the

WAN.

This value is referenced as the default weight value when using the

Least Used

or

Persistence (Auto)

algorithms in

Outbound Policy

with

Managed by Custom Rules

chosen.

IPv6

IPv6

IPv6 support can be enabled on one of the available Ethernet WAN ports. On this screen,

you can choose which WAN will support IPv6.

To enable IPv6 support on a WAN, the WAN router must respond to stateless address

auto configuration advertisements and DHCPv6 requests. IPv6 clients on the LAN will

acquire their IPv6, gateway, and DNS server addresses from it. The device will also

acquire an IPv6 address for performing ping/traceroute checks and accepting Web Admin

accesses.

12.1

Connection Method(s)

There are four possible connection methods:

1.

DHCP

2.

Static IP

3.

PPPoE

4.

Mobile Internet Connection (for USB WAN)

12.1.1 DHCP Connection

The DHCP connection method is suitable if your ISP provides an IP address automatically using DHCP

(e.g.,cable, metro Ethernet, etc.).

DHCP Settings

DNS Servers

Each ISP may provide a set of DNS servers for DNS lookups. This setting specifies the

DNS (Domain Name System) servers to be used when a DNS lookup is routed through this

connection.

Selecting

Obtain DNS server address automatically

results in the DNS servers

assigned by the WAN DHCP Server being used for outbound DNS lookups over the

connection. (The DNS servers are obtained along with the WAN IP address assigned by

the DHCP server.)

When

Use the following DNS server address(es)

is selected, you may enter custom DNS

server addresses for this WAN connection into the

DNS server 1

and

DNS server 2

fields.

Hostname

(Optional)

If your service provider's DHCP server requires you to supply a hostname value upon

acquiring an IP address, you may enter the value here. If your service provider does not

provide you with a hostname, you can safely bypass this option.

Please refer to sections 12.3, 12.4, 12.5, and 12.6 for details about

WAN Health Check, Bandwidth

Allowance Monitor, Additional Public IP Settings, and Dynamic DNS Settings

.

Default Gateway

These settings specify the information required in order to communicate on the Internet

via a fixed Internet IP address.

The information is typically determined by and can be obtained from your ISP.

DNS Servers

Each ISP may provide a set of DNS servers for DNS lookups. This field specifies the

DNS (Domain Name System) servers to be used when a DNS lookup is routed through

this connection.

You can input the ISP-provided DNS server addresses into the

DNS server 1

and

DNS

server 2

fields.

If no address is entered here, this link will not be used for DNS lookups.

Please refer to Section 12.3, 12.4, 12.5, and 12.6 for details about
