WAN1:
Select “ADSL” “EWAN” or “3G” mode for WAN1.
WAN2:
Select the left WAN mode for WAN2 as backup port. For example, if 3G is set for main port, then
there can be no option for failover/failback.
Time Schedule:
A self defined time period. You may specify a time schedule for failover/failback
functioning. For setup and detail, refer to Time Schedule section.
Keep Backup Interface Connected:
Select Enable this function, the backup WAN port will connect
always.
Connectivity Decision:
Set how many times of probing failed to switch backup port.
Failover Probe Cycle:
Set the time duration for the
Failover Probe Cycle
to determine when the router
will switch to the backup connection (backup port) once the main connection (main port) fails.
Note
:
The time set is for each probe cycle, but the decision to change to the backup port is
determined by
Probe Cycle duration
multiplied by
connection Decision amount
(e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Failback Probe Cycle:
Set the time duration for the
Failback Probe Cycle
to determine when the router
will switch back to the main connection (main port) from the backup connection (backup port) once the
main connection is communicating again.
Note
:
The time set is for each probe cycle, but the decision to change to the backup port is
determined by
Probe Cycle duration
multiplied by
Connection Decision amount
(e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Detect Rule:
Rule 1. ADSL Down
Rule 2. Ping Fail
No Ping:
It will not send any ping packet to determine the connection. It means to disable the ping
fail detection.
Ping Gateway:
It will send ping packet to gateway and wait response from gateway in every
“Probe Cycle”.
Ping Host:
It will send ping packet to specific host and wait response in every “Probe Cycle”. The
host must be an IP address.

WAN Profile
ADSL
PPPoE Connection
PPPoE (PPP over Ethernet) provides access control in a manner which is similar to dial-up services
using PPP.
Profile Port:
Select the profile port
as ADSL
.
Protocol:
The ATM protocol will be used in the device.
Description:
A given name for the connection.
VPI/VCI:
Enter the information provided by your ISP.
ATM Class:
The Quality of Service for ATM layer.
Username:
Enter the username provided by your ISP. You can input up to
128
alphanumeric characters
(case sensitive). This is in the format of “username@ispname” instead of simply “username”.
Password:
Enter the password provided by your ISP. You can input up to
128
alphanumeric characters
(case sensitive).
Service Name:
This item is for identification purposes. If it is required, your ISP provides you the
information. Maximum input is
15
alphanumeric characters.
NAT:
The NAT (Network Address Translation) feature allows multiple users to access the Internet through
a single IP account, sharing the single IP address. If users on your LAN have public IP addresses and
can access the Internet directly, the NAT function can be disabled.
IP (0.0.0.0:Auto):
Your WAN IP address. Leave this at 0.0.0.0 to obtain automatically an IP address from
your ISP.
Auth. Protocol:
Default is
Auto
. Your ISP should advises you on whether to use
Chap
or
Pap.
Connection:
Always on:
If you want the router to establish a PPP session when starting up and to
automatically re-establish the PPP session when disconnected by the ISP.
Connect on Demand:
If you want to establish a PPP session only when there is a packet
requesting access to the Internet (i.e. when a program on your computer attempts to access the

64
Internet).
Idle Timeout:
Auto-disconnect the broadband firewall gateway when there is no activity on the line for a
predetermined period of time.
Detail:
You can define the destination port and packet type (TCP/UDP) without checking by
timer. It allows you to set which outgoing traffic will not trigger and reset the idle timer.
MTU:
Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers)
that IP will attempt to send through the interface.
RIP:
RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
TCP MSS Clamp:
This option helps to discover the optimal MTU size automatically. Default is enabled.
MAC Spoofing:
This option is required by some service providers. You must fill in the MAC address that
specify by service provider when it is required. Default is disabled.
Obtain DNS:
A Domain Name System (DNS) contains a mapping table for domain name and IP
addresses. DNS helps to find the IP address for the specific domain name. Check the checkbox to obtain
DNS automatically.
Primary DNS:
Enter the primary DNS.
Secondary DNS:
Enter the secondary DNS.
Default Route:
Check to enable default route.
IPv6:
check to enable IPv6 service. If enabled, please set the IPv6 Address, Ipv6 DNS, similar as IPv4.
IPv6 Address:
type the IPv6 address from your ISP, or get it automatically.
”::” means to obtain IPv6
address automatically.
Obtain IPv6 DNS:
check
Automatic
to obtain DNS automatically.
If not, please type the exact one in
the Primary field.
