Vendor Class to send
when requesting
DHCP
Identifies the vendor of a DHCP client for the enhancement of vendor-specific
DHCP functionality. The following three options are specific to the PPTP and
PPPoE protocols:
Physical Settings Interface – Chooses which physical interface to use for the WAN
zone. This can be the Ethernet Adapter “eth0” or “eth1” that corresponds to each of
the two ports on the device for example. It could also be set as the Wireless Network.
If there is a physical interface selected for the WAN zone, this can be referred to
as the “NAT mode”, because network address translation occurs between the WAN
zone and the LAN zone. If No Interface is selected for the WAN zone, all interfaces
would be within the LAN zone. This may also be referred to as the “Bridge Mode”.
11.2 Interfaces – LAN
11.2.1 Common Configuration
General Setup
Status Shows a summary of the current LAN port status, which includes uptime, MAC address,
received bytes and packets, transmitted bytes and packets, and IPv4 address.
Protocol Chooses between Static address, where you can specify the device IP address, or DHCP
client, where the device obtains it IP address automatically. Static address is necessary
if other devices obtain internet connection through this device. Static address is also
recommended if you wish to configure the device via the LuCI web interface.
Note: After modifying the Protocol option, please click the “Switch protocol” button. If using
the Static address protocol, please fill in the IPv4 address, IPv4 netmask, IPv4 gateway, and a
custom DNS server. Finally, please click the “Save & Apply” button.
Protocol – Static address
IPv4 address Sets the IP address of the device e.g. 192.168.10.1, where you can access the Radios
configuration web page.
IPv4 netmask Sets the subnet mask e.g. 255.255.255.0. The IP address and netmask together
determine the subnet or network ID e.g. 192.168.10.0/24. Two devices must be in the
same subnet in order to establish a (Layer 2) link between them.
IPv4 gateway Specifies the IP address of the remote router that allows the device's shell to gain
internet access.
IPv4 broadcastSpecifies the IPv4 broadcast address, optional.
Use custom
DNS servers
Configures the IP address of the DNS servers e.g. 165.21.100.88 for the SingNet DNS
server in Singapore or 8.8.8.8 for the Google DNS server in the USA. The computers in
the same subnet as this device can then set this device's IP address as their preferred
DNS server to obtain the same DNS service.
Protocol – DHCP client
The Dynamic Host Configuration Protocol (DHCP) is a standardized networking protocol used
by servers on an IP network to allocate IP addresses automatically to client devices.
