You may also configure DNS settings when using the Router in DHCP mode ( Advanced > DNS Setup ). When “Obtain DNS server address
automatically“ is clicked under DNS Server Configuration on the DNS Setup window, the Router will automatically relay DNS settings to properly
configured DHCP clients. To manually enter DNS IP addresses, click the “Use the following DNS server addresses“ radio button and type in a
Preferred DNS Server and Alternate DNS Server in the fields provided. The manually configured DNS settings will be supplied to clients that are
configured to request them from the Router.
Follow the instructions below according to which of the above DHCP options you want to use. When you have configured DHCP as you want, click
the
Apply Settings button to commit the new settings.
Use the Router for DHCP
To use the built-in DHCP server, tick the Enable DHCP Server check box in the DHCP Server Settings (Optional) section if it is not already selected.
The IP address pool settings can be adjusted. The DHCP IP Address Range starts with the lowest available IP address (default = 192.168.1.2). If
you change the IP address of the Router this will change automatically to be 1 more that the IP address of the Router. The DHCP IP Address Range
ends with the highest IP address number in the pool. Type in the DHCP Lease Time in the entry field provided. This is the amount of time in hours
that a workstation is allowed to reserve an IP address in the pool if the workstation is disconnected from the network or powered off.
Disable the DHCP Server
To disable DHCP, deselect the Enable DHCP Server check box in the DHCP Server Settings (Optional) section and click the Apply Settings button.
Choosing this option will gray out most of the setting options on this window and require that workstations on the local network be configured
manually or use another DHCP server to obtain IP settings.
If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. You will need to use the Router’s IP address as the
Default Gateway for the workstation in order to provide Internet access.
Add Static DHCP
To add a static DHCP entry to the Static DHCP List, tick the Enable check box in the Add Static DHCP (Optional) section, type in an IP Address,
either click the
Copy Your PC’s MAC Address button or manually enter a MAC Address, enter a Computer Name if desired, and click the Save
button. Click Clear to reset the values in this section. To delete an entry from the Static DHCP List, tick the corresponding check box and then click
the Remove Selected button. To modify a Static DHCP List entry, click the corresponding Edit hyperlink and then enter the information in the
appropriate fields in the Add Static DHCP (Optional) section.
