IP Subnet Mask
This field is used to configure the IP Subnet Mask
for the router’s local area network. By default the
subnet mask is 255.255.255.0.
DHCP Server
This option allows to you configure whether the
router acts as a Dynamic Host Control Protocol
(DHCP) server – handling the IP address of
connected devices or computer automatically. This
is enabled by default.
Select ‘Enable’ to use the router as a DHCP server.
When a computer connects to the router, the router
assigns the local area IP addresses automatically.
Select ‘Disable’ to switch off DHCP on the router. All
devices connecting to the router must be
individually configured with static IP addresses in
order to access the network and Internet.
Lease Time
This dropdown allows you to configure the amount
of time an IP address is allocated to a connected
device using DHCP. By default, the IP address is
allocated for two days, after which time the IP
address will be automatically renewed by the router.
You can select lease times from Ten Minutes to Two
Weeks, or select the ’Forever’ option, meaning that
the IP address for a connected device will never
automatically be re-assigned by the router.
Start IP
This field is used to configure the starting range of
IP addresses allocated to connected devices via
DHCP. The default starting range is ‘2’ (i.e.
192.168.1.2 for the default VLAN).
End IP
This field is used to configure the end range of IP
addresses allocated to connected devices via DHCP.
The default end range is ‘254’ (i.e. 192.168.1.254 for
the default VLAN).
Domain Name
This field is used to configure the domain name of
your local network (if required) for DHCP. This value
is ‘default’, and should not need to be changed for
most operating systems.
Add Reserved IP
Click this link to reserve an IP address for a
computer or device. Once an IP address has been
reserved for that device, every time the device
connects to your router, it will be assigned the same
IP address.
How to reserve an IP address for a computer or a device
You may wish to ensure that when a device or computer connects to your router, it is given
the same IP address each time. This is useful if you are setting up port forwarding, access
control rules or a DMZ for a particular device. For example if you want to set up a computer
as a web server and require port forwarding rules to allow this, you will need to ensure that
computer has the same IP address every time it connects to your router.
You can reserve addresses for up to 32 devices.
