Configuring Network WAN Configuration
Downstream
Bandwidth
Specify the downstream bandwidth of the WAN port. This value is the upper limit of
the Maximum Downstream Bandwidth on Transmission > Bandwidth Control page.
Also, this value determines the bandwidth ratio of each WAN port after Bandwidth
Based Balance Routing is enabled on Transmission > Load Balancing > Basic
Settings page.
MTU Specify the MTU (Maximum Transmission Unit) of the WAN port.
MTU is the maximum data unit transmitted in the physical network. When Dynamic
IP is selected, MTU can be set in the range of 576-1500 bytes. The default value is
1500.
Primary/
Secondary DNS
(Optional) Enter the IP address of the DNS server provided by your ISP.
VLAN Add the WAN port to a VLAN. Generally, you don’t need to manually configure it
unless required by your ISP.
VLAN ID If VLAN for the WAN port is enabled, you need to enter a VLAN ID. Then the WAN
port is automatically assigned to the VLAN. By default, the egress rule of the VLAN
is UNTAG, so the packets are transmitted by the WAN port without VLAN tags. If
you want the WAN port to transmit packets with VLAN tag, you need to configure its
egress rule as TAG. To configure VLANs, go to Network > VLAN > VLAN .
Get IP using
Unicast DHCP
The broadcasting requirement may not be supported by a few ISPs. Select this
option if you can not get the IP address from your ISP in the normal DHCP process.
This option is not required generally.
Negotiation
Mode
Select the negotiation mode for the port. You can set the mode as Auto, or manually
set the speed and duplex mode for the port. It is recommended to configure both
devices of a link to work in Auto-Negotiation mode or manually configure them to
work in the same speed and duplex mode.
If the two devices at both sides work in Auto mode, they will advertise their speed
and duplex abilities to each other, and negotiate the optimal speed and duplex mode.
If the local device works in Auto mode while the peer device does not, the local
device will automatically detect and match the speed with the peer device. The local
device will work in half-duplex mode, no matter what duplex mode the peer device is
in.
Flow Control With this option enabled, when a device gets overloaded it will send a PAUSE frame
to notify the peer device to stop sending data for a specified period of time, thus
avoiding the packet loss caused by congestion.
Connect/
Disconnect
Click the button to active/terminate the connection.
