IP address range:
If machines on your LAN use different IP address ranges
(for example, 172.16.2.0 or 10.0.0.0), you can add aliases to the LAN port to
give PCs on those networks access to the Internet. This allows the RV220W
to act as a gateway to additional logical subnets on your LAN. You can
assign the RV220W an IP address on each additional logical subnet.

STEP 1
In the
Network
section, keep the default
Host Name
, or enter a new name to
identify your router. This field allows alpha-numeric characters and the hyphen.
The default host name consists of the word “router” followed by the last 3 bytes of
LAN MAC address (in Hex-decimal form). This allows the Cisco FindIT Network
Discovery Utility to identify Cisco Small Business devices on the LAN.
STEP 2
In the
LAN (Local Network) Configuration
section, keep the default
IP Address
and
Subnet Mask
, or change them as needed for your network.
Note:
If you change the LAN IP address, you will need to use the new IP address to
launch the configuration utility. You may need to release and renew the IP address
of your PC, if using DHCP, or configure a static IP address in the same subnet as
the RV220W.
STEP 3
In the
DHCP
section, choose the
DHCP Mode
and enter the required settings.
Note:
If you need to reserve IP addresses for devices on your network, click the
Configure Static DHCP
button. For more information, see
Static DHCP, page 28

DHCP Server
—Choose this option to allow the Cisco RV220W to
dynamically assign IP addresses to devices in the network. By default, the
Cisco RV220W functions as a DHCP server to the hosts on the Wireless LAN
(WLAN) or LAN network and assigns IP and DNS server addresses. With
DHCP enabled, the RV220W's IP address serves as the gateway address to
your LAN. The PCs in the LAN are assigned IP addresses from a pool of
addresses. Each address is tested before it is assigned to avoid duplicate
addresses on the LAN. If you choose this option, enter this information:
-
Domain Name
—Enter the domain name for your network (optional).
-
Starting and Ending IP Address
—Enter the first and last of the
contiguous addresses in the IP address pool. Any new DHCP client
joining the LAN is assigned an IP address in this range. You can save part
of the range for PCs with fixed addresses. These addresses should be in
the same IP address subnet as the RV220W's LAN IP address.
