802.1p

This field is available only when VLAN is enabled. 

Enter the IEEE 802.1p priority level for this WAN interface connection.

DSCP

Enter a DSCP (DiffServ Code Point) value to have the Device add it in the packets sent by 
this WAN interface.

IP Address

You can use these options when you set the Mode field to Router and the IPv6/IPv4 
Dual Stack field to IPv4 or IPv4/IPv6.

Select Obtain an IP Address Automatically if the ISP assigns you a dynamic IP 
address; otherwise select Static IP Address and type your ISP assigned IP address in the 
IP Address field below. 

Static IP Address  Select this option If the ISP assigned a fixed IP address. 

IP Address

Enter the static IP address provided by your ISP.

Subnet Mask  Enter a subnet mask in dotted decimal notation. 

Gateway IP 

Address

Specify a gateway IP address (supplied by your ISP).

Primary / 

Secondary 

DNS 

Set how the Device gets the IP addresses of the DNS servers it uses.

UserDefined - enter a static IP address.

Obtained From ISP - when the Device gets its IP address automatically, you can select 
this to have it also get the DNS server address.

None - the Device does not use the DNS server entry. 

IPv6 Address

Obtain an IP 
Address 
Automatically

Select this option if you want to have the Device use the IPv6 prefix from the connected 
router’s Router Advertisement (RA) to generate an IPv6 address. 

Static IP Address Select this option if you have a fixed IPv6 address assigned by your ISP.

DHCP IPv6

Select DHCP if you want to obtain an IPv6 address from a DHCPv6 server.

The IP address assigned by a DHCPv6 server has priority over the IP address automatically 
generated by the Device using the IPv6 prefix from an RA.

Select SLAAC (Stateless address autoconfiguration) to have the Device use the prefix to 
automatically generate a unique IP address that does not need to be maintained by a 
DHCP server.

DHCP PD 

Select Enable to use DHCP PD (Prefix Delegation) to allow the Device to pass the IPv6 
prefix information to its LAN hosts. The hosts can then use the prefix to generate their 
IPv6 addresses.

IPv6 Address

With Static IP Address enabled, enter the IPv6 address of the Device in the WAN.

Prefix Length

With Static IP Address enabled, enter the IPv6 prefix length in the WAN.

IPv6 Default 
Gateway

With Static IP Address enabled, enter the IPv6 address of the default gateway

IPv6 DNS 
Server1

With Static IP Address enabled, enter the primary DNS server IPv6 address for the 
Device.

IPv6 DNS 
Server2

With Static IP Address enabled, enter the secondary DNS server IPv6 address for the 
Device.

Connection

Keep Alive

Select Keep Alive when you want your connection up all the time. The Device will try to 
bring up the connection automatically if it disconnects.

Connect on 
Demand

specify an idle time-out in the Max Idle Timeout field.
