2. Enter a LAN IP address and subnet mask for the router.
3. Click <
Apply> to save the LAN IP address.
If you were using an Ethernet connection for the current
session, and changed the IP address, the connection will be
terminated.
4. Reconfigure your PCs, if necessary, so that their IP addresses place
them in the same subnet as the new IP address of the LAN port.
See the Quick Start Guide chapter, 3.2 Part 2 — Configuring Your
Computers, for instructions.
5. Enter the new IP address in your Web browser’s address/location box
to log into the Configuration Manager.
5.2 Dynamic Host Control Protocol (DHCP)
5.2.1 What is a DHCP?
DHCP is a protocol that enables network administrators to centrally
manage the assignment and distribution of IP information to computers on
a network.
When you enable DHCP on a network, you allow a device, such as the
router, to assign temporary IP addresses to your computers whenever they
connect to your network. The assigning device is called a DHCP server,
and the receiving device is a DHCP client.
If you followed the Quick Start Guide instructions, you
either configured each LAN PC with an IP address, or you
specified that it will receive IP information dynamically
(automatically). If you chose to have the information
assigned dynamically, then you configured your PCs as
DHCP clients that will accept IP addresses assigned from a
DCHP server such as the Internet Security Router.
The DHCP server draws from a defined pool of IP addresses and “leases”
them for a specified duration to your computers when they request an
Internet session. It monitors, collects, and redistributes the addresses as
needed.
On a DHCP-enabled network, the IP information is assigned dynamically
rather than statically. A DHCP client can be assigned a different address
from the pool each time it reconnects to the network.
