MAC Address Cloning When enabled, you can change
the MAC address of the respective interface. This is
especially useful if your ISP only assigns one valid IP
address and it is associated to a specific MAC address. This
is usually used by cable operators or some WISPs.
•
MAC Address Enter the MAC address you want to clone
to the respective interface. This becomes the new MAC
address of the interface.
LAN Network Settings
LAN Interface The interface is displayed. Click Del to
delete the interface. If there is no interface selected, select
an interface from the Add LAN drop-down list, and click
Add.
IP Address The IP address of the LAN (including WLAN)
interface connected to the local network. This IP will
be used for routing of the local network; it will be the
gateway IP for all the devices on the local network. This IP
address is used for management of the device.
Netmask Defines the device IP classification for the
chosen IP address range. 255.255.255.0 is a typical
netmask value for Class C networks, which support the
IP address range of 192.0.0.x to 223.255.255.x. A Class
C network netmask uses 24 bits to identify the network
(alternative notation “/24”) and 8 bits to identity the host.
MTU (Available in Simple view.) The Maximum
Transmission Unit (MTU) is the maximum packet size (in
bytes) that a network can transmit. The default is 1500.
DHCP Server The built-in DHCP server assigns IP
addresses to clients connected to the wireless interface
and LAN interface while the device is operating in Access
Point or AP‑Repeater wireless mode. The built-in DHCP
server assigns IP addresses to clients connected to the
LAN interface while the device is operating in Station
mode.
• Disabled The device does not assign local IP addresses.
• Enabled The device assigns IP addresses to client
devices on the local network.
- Range Start and End Determines the range of IP
addresses assigned by the DHCP server.
- Netmask Defines the device IP classification for the
chosen IP address range. 255.255.255.0 is a typical
netmask value for Class C networks, which support
an IP address range of 192.0.0.x to 223.255.255.x. A
Class C network netmask uses 24 bits to identify the
network (alternative notation “/24”) and 8 bits to
identity the host.
- Lease Time The IP addresses assigned by the DHCP
server are valid only for the duration specified by
the lease time. Increasing the time ensures client
operation without interruption, but could introduce
potential conflicts. Decreasing the lease time avoids
potential address conflicts, but might cause more
slight interruptions to the client while it acquires a
new IP address from the DHCP server. The time is
expressed in seconds.
- DNS Proxy The Domain Name System (DNS) proxy
server forwards the DNS requests from the hosts on
the local network to the DNS server.
- Primary DNS If the DNS proxy is disabled, specify the
local IP address of the primary DNS server.
- Secondary DNS If the DNS proxy is disabled, specify
the IP address of the secondary DNS server. This entry
is optional and used only if the primary DNS server is
not responding.
