Follow these steps to configure IP Address Serving:
•
If you enabled IP Address Serving, then DHCP, BootP clients and Dynamic WAN clients are automatically
enabled.
•
The IP Address Serving Mode pop-up menu allows you to choose the way in which the Router will serve IP
addresses. The device can act as either a DHCP Server or a DHCP Relay Agent. (See
on page 7-28 for more information.) In most cases, you will use the device to serve its own pool of IP
addresses, hence DHCP Server is the default. Address serving can also be disabled.
•
Select Number of Client IP Addresses and enter the total number of contiguous IP addresses that the
Router will distribute to the client machines on your local area network. Twelve-user models are limited to
twelve IP addresses.
In the screen example shown above, five Client IP addresses have been allocated.
•
Select 1st Client Address and enter the first client IP address that you will allocate to your first client
machine. For instance, on your local area network you may want to first figure out which machines are going
to be allocated specific static IP addresses so that you can determine the pool of IP addresses that you will
be serving addresses from via DHCP, BootP, and/or Dynamic WAN.
Example: Your ISP has given your Router the IP address 192.168.6.137, with a subnet mask of
255.255.255.248. The subnet mask allocated will give you six IP addresses to use when connecting to the
ISP over the Internet. Your address range will be from .137 – .143. In this example you would enter
192.168.6.138 as the 1st Client Address, since the gateway itself must have an IP address.
•
To enable DHCP, select Serve DHCP Clients and toggle it to Yes. DHCP serving is automatic when IP
Address Serving is enabled.
•
The DHCP Next-Server field allows you to enter the IP address of the next server in the boot process,
which is typically a Trivial File Transfer Protocol (TFTP) server.
