Configure a Wide Area Network (WAN)
Configuring a Wide Area Network (WAN) involves configuring the following items:
Required configuration items
- The interface type: Ethernet.
- The firewall zone:External.
- The network device that is used by the WAN.
- Configure the WAN as a DHCP client.
Additional configuration items
Additional IPv4 configuration:
- The metric for IPv4 routes associated with the WAN.
- The relative weight for IPv4 routes associated with the WAN.
- The IPv4 management priority of the WAN. The active interface with the highest management priority will have its address reported as the preferred contact address for central management and direct device access.
- The IPv4 Maximum Transmission Unit (MTU) of the WAN.
- When to use DNS servers for this interface.
- Whether to include the Connect EZ device's hostname in DHCP requests.
IPv6 configuration:
- The metric for IPv4 routes associated with the WAN.
- The relative weight for IPv4 routes associated with the WAN.
- The IPv4 management priority of the WAN. The active interface with the highest management priority will have its address reported as the preferred contact address for central management and direct device access.
- The IPv4 Maximum Transmission Unit (MTU) of the WAN.
- When to use DNS servers for this interface.
- Whether to include the Connect EZ device's hostname in DHCP requests.
-
MAC address blacklist and whitelist.

- For Type, select
- Optional IPv4 configuration items:
- Set the Metric.
See Configure WAN priority and default route metrics for further information about metrics.
- For Weight, type the relative weight for default routes associated with this interface. For multiple active interfaces with the same metric, Weight is used to load balance traffic to the interfaces.
- Set the Management priority. This determines which interface will have priority for central management activity. The interface with the highest number will be used.
- Set the MTU.
- For Use DNS, select one of the following:
- Always: DNS will always be used for this WAN; when multiple interfaces have the same DNS server, the interface with the lowest metric will be used for DNS requests.
- When primary default route: Only use the DNS servers provided for this interface when the interface is the primary route.
- Never: Never use DNS servers for this interface.
- Enable DHCP Hostname to instruct the Connect EZ device to include the device's system name with DHCP requests as the Client FQDN option. The DHCP server can then be configured to register the device's hostname and IP address with an associated DNS server.
- See RFC4702 for further information about DHCP server support for the Client FQDN option.
- See Configure system information for information about setting the Connect EZ device's system name.
- Click to expand IPv4.
-
(Optional) Configure IPv6 settings:

- Optional IPv4 configuration items:
- Set the IP metric:
(config network interface my_wan)> ipv4 metric num (config network interface my_wan)>
See Configure WAN priority and default route metrics for further information about metrics.
Set the relative weight for default routes associated with this interface. For multiple active interfaces with the same metric, the weight is used to load balance traffic to the interfaces.
(config network interface my_wan)> ipv4 weight num (config network interface my_wan)>
- Set the management priority. This determines which interface will have priority for central management activity. The interface with the highest number will be used.
(config network interface my_wan)> ipv4 mgmt num (config network interface my_wan)>
- Set the MTU:
(config network interface my_wan)> ipv4 mtu num (config network interface my_wan)>
- Configure how to use DNS:
(config network interface my_wan)> ipv4 use_dns value (config network interface my_wan)>
where value is one of:
- always: DNS will always be used for this WAN; when multiple interfaces have the same DNS server, the interface with the lowest metric will be used for DNS requests.
- primary: Only use the DNS servers provided for this interface when the interface is the primary route.
- never: Never use DNS servers for this interface.
- Set the IP metric:
See Configure WAN priority and default route metrics for further information about metrics.
- IPv4 support is enabled by default. To disable:
