Specify the downstream bandwidth of the WAN port. The value configured here is the
lower limit of the "Maximum Downstream Bandwidth" on Transmission > Bandwidth
Control > Bandwidth Control page, to make "Bandwidth Control" take effect, please
ensure this parameter is set correctly.
Specify the MTU (Maximum Transmission Unit) of the WAN port.
MTU is the maximum data unit transmitted in the physical network. When PPPoE is
selected, MTU can be set in the range of 576-1492 bytes. The default value is 1492.
Optional. Enter the service name. This parameter is not required unless provided by
your ISP. It is null by default.
Optional. Enter the IP address of the DNS server provided by your ISP.
Add the WAN port to a VLAN. Generally, you don't need to manually configure it
unless required by your ISP.
By default, the WAN port is automatically assigned to a VLAN, and 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 create
the corresponding VLAN first and configure its egress rule as TAG, then manually
add the WAN port to that VLAN. To create VLANs, go to Network > VLAN > VLAN.
Note: When using the IPTV function, either in Bridge mode or Custom mode,
the router will automatically create corresponding VLANs after you finished the
configuration, and add port 1 (WAN 1) to the VLANs. Users cannot then manually
select the VLAN that WAN 1 belongs to.
Secondary connection is required by some ISPs. Select the connection type required
by your ISP.
None: Select this if the secondary connection is not required by your ISP.
Dynamic IP: Select this if your ISP automatically assigns the IP address and subnet
mask for the secondary connection.
Static IP: Select this if your ISP provides you with a fixed IP address and subnet mask
for the secondary connection.
Click the button to active/terminate the connection.
