If users want to know DNS Servers obtained from ISP, It can be found
in
“
Network > Status > WAN Information > DNS Server
”
Primary/Secondary/Tertiary DNS:
If the checkbox
“
From ISP
”
is not ticked, users can
designate the DNS server for DHCP clients. Two pictures below are captured from CPE and a
PC in LAN; DNS fields are
“
1.1.1.1
”
,
“
2.2.2.2
”
and
“
3.3.3.3
”
. Clients
’
DNS request will be
directly sent to the first operative server in the order of primary, secondary and tertiary
DNS.
Network > DHCP Server > not From ISP
Network > DHCP Server > not From ISP
“1.2.3.4”
,
“5.6.7.8”
and
“2.4.6.8”
are examples.

DHCP Lease Time:
The life time of the IP assigned by DHCP server( range: 2
minutes-365days)
Lease Reservation Table:
This table records the mapping of MAC and IP addresses. Clients
with the specific MAC address in the table would get the corresponding IP address. Click
“
Add +
”
button to add a new mapping, clicking
“
Delete
”
icon (
) to delete it. To enable
the mapping, users have to tick the
“
Enable
”
checkbox.
An example is illustrated below. If a client with MAC Address
“
11:22:33:44:55:66
”
requests
IP, DHCP server will assign IP
“
192.168.15.123
”
and the host name
“
Example
”
to it.

Network | QoS (Not available in bridge mode)
Network > QoS
QoS stands for
“
Quality of Service
”
, different network services can be prioritized. Users have to
add rules which designate that network flow through certain port ranges or IP address range
would have a guaranteed sending rate. Click
“
Add +
”
button to add a new rule, clicking
“
Delete
”
icon (
) to delete the rule.
Enable QoS:
Enable/disable QoS.
Enable VoIP QoS:
set generic rules for VoIP service, like UDP and TCP port 5060, 11720
…
.
Name:
Name of the rule.
Priority:
Priority of each rule,
“
1
”
is the highest priority,
“
255
”
is the lowest priority.
Enable:
Enable/Disable the rule.
Interface:
The interface that the rule is applied to.
Min Rate:
The guaranteed sending rate if the traffic needs at least min rate and the
bandwidth is abundant.
Max Rate:
The maximum sending rate
”
if the bandwidth is abundant
.

About
Min Rate
and
Max Rate
, we can discuss this in 3 cases.
For example, Min Rate=
50
kbps
Max Rate=
100
kbps
1.
If
20
kbps is needed, the traffic will only get
20
kbps, CPE will not
give it
50
kbps (50 kbps=Min Rate, this can prevent wasting
bandwidth)
2.
If
60
kbps is needed, the traffic at least
gets
50
kbps and CPE tries
to satisfy
60
kbps requirement.
3.
If
200
kbps is needed, the traffic will only get
100
kbps due to max
rate constraint.
Mode:
Only protocol QoS
Protocol:
“
TCP
”
,
“
UDP
”
,
“
ICMP
”
and
“
ANY
”
. ANY includes TCP, UDP and ICMP.
Source/ Destination Port Range and Source/ Destination IP Range:
The port and IP range
of the traffic that needs QoS.
Source/Destination Port and Source/Destination IP can be an
empty
value
, which means
“
DON’T
CARE
”
.
