Port Management
Port Setup
The default port settings will be sufficient for most small businesses, but you
can still use the
Port Management > Port Setup
page to customize these settings°
You can disable a port or customize its priority, speed, duplex mode, and auto-
negotiation settings° You can also enable port-based VLANs to control traffic
between devices on your network°
NOTE:
Remember to click

Enter the following settings, as needed:
Disable:
Check this box to disable a port° By default, all ports
are enabled°
Priority:
(for LAN ports
only)
Use this setting to ensure Quality of Service by
prioritizing the traffic for devices on particular ports°
For example, you might assign High priority to a
port that is used for gaming or videoconferencing°
For each port, select the appropriate priority level,
High or Normal° The default setting is Normal°
Speed:
If you want to adjust this setting, uncheck the
Enable box in the Auto Negotiation column° Then
select the port speed: 10Mbps or 100Mbps°
Duplex:
If you want to set the duplex mode, first uncheck
the Enable box in the Auto Negotiation column to
disable auto-negotiation° Select the duplex mode,
Half or Full°
Auto Neg.:
Check the Enable box to allow the router to auto-
negotiate connection speeds and duplex mode°
This feature is enabled by default°
VLAN:
(for LAN ports

802.1Q
The router supports up to five sets of VLANs, which are used to divide networks
into several segments° Dividing networks makes them easier to manage and
enhances performance and security through isolation°
802°1Q is a protocol for carrying VLAN traffic on an Ethernet° 802°1Q will append
a tag which includes VLAN membership information within the original packet°
The devices can communicate with others with the same VLAN ID° In this way,
it will make the network manageable and secure°
Go to Configuration > Port Management > 802°1Q°
802.1Q LAN Status
VLAN ID:
Indicates VLAN ID (VID)°
The first VLAN with VID1 is default VLAN and
cannot be deleted°
Description:
The name of the VLAN°
Inter VLAN Routing:
Every set of VLAN has its own DHCP address pool°
If VLAN is enabled to communicate with other
sets of VLAN, the status is shown as
Enabled.
The
default value is
Disabled
°
Device Management:
If this VLAN is allowed to open Web GUI, the status
will be shown as
Enabled.
The default value is
Disabled.
LAN1 ~ LAN4:
Indicates VLAN status of physical LAN port° It could
be
Tagged,
Untagged
o
r Excluded
°
Config.:
To configure existing VLAN°
Del.:
To delete existing VLAN°
Add:
Click

802.1Q LAN Configuration
Click Edit to change an existing VLAN configuration or click Add to set up a new
set of VLAN°
VLAN ID:
Input VID (range:2~4092) of the VLAN°
Description:
Give a name to the VLAN°
Inter VLAN Routing
:
Every set of VLAN has its own DHCP address pool°
Select
Enabled
so that the VLAN is allowed to
communicate with other sets of VLAN° The default
value is
Disabled
°
Device
Management:
Select Enabled to allow the VLAN access to the Web
GUI° The default value is
Disabled.
LAN1 ~ LAN4:
Configure VLAN status of physical LAN ports° There
can only be one untagged VID for a LAN port°
For example, if we configure LAN2 as Untagged
for VID2, LAN2 for VID1 will be changed as Tagged
automatically°
If we configure LAN2 for VID1 as Tagged, LAN2 for
VID2 will be changed as Untagged automatically°
If there is only one VID, changing status to Tagged for
any LAN port is not allowed°

Firewall
Turn on/off the firewall.
SPI (Stateful Packet Inspection)
Enables
the
packet
automatic
authentication detection technology.
The firewall operates mainly at the
network layer. By running the dynamic
authentication for each connection, it
will also perform an alarming function
for application procedure. Meanwhile,
the packet authentication firewall may
decline the connections that use non-
standard communication protocol.
DoS (Denial of Service)
Prevents DoS attacks such as SYN
Flooding, Smurf, LAND, Ping of Death,
IP Spoofing and so on.
Block WAN Request
When enabled, shuts down outbound
ICMP and abnormal packet responses
in
connection.
Default
value
is
enabled, which prevents users from
pinging the WAN IP from outside the
network.
Remote Management
Must be enabled to enter the device’s
Web-based
UI
remotely.
A
valid
external IP address (WAN IP) for the
device should be filled in and the
modifiable default control port should
be adjusted (the default is set to 80,
modifiable).
HTTPS Multicast Pass Through
HTTPS is more secure.
This feature
allows user to turn on HTTPS.
There are many audio and visual
streaming media on the network.
Broadcasting may allow the client end
to receive this type of packet message
format. This feature is off by default.
UPnP
This feature allows users to enable/
disable UPnP.
