Configuring a NAT router for DHCP
The following instructions were written for the Linksys Etherfast Cable/DSL Router model Numbers
BEFSRU31, BEFSR41 v.2, and BEFSR11. The steps will be similar for other NAT routers. Refer to the
router’s
User’s Guide
for the specific instructions.
1.
Retrieve the
Linksys Etherfast Cable/DSL Router User’s Guide
that came with the router.
2.
The user’s PC must be configured to use DHCP (or, as stated in the
Windows
network properties,
“Obtain an IP address automatically”):
• Click
on
the
Start
Menu, choose
Settings
, then choose
Control Panel.
• Double
click
the
Network
icon. The Network Dialog Box appears.
• Choose
the
TCP/IP
protocol. (If you do not see TCP/IP, please see page J.1 of these
instructions.) Multiple instances of the TCP/IP protocol bound to different adapters may appear. If
so double click the TCP/IP that appears to the network interface card (NIC) installed in the PC.
• Click on the IP address tab, and ensure that the bullet next to “
Obtain IP address
Automatically
” is filled in.
• Click
OK
, and reboot the PC if needed.
3.
Connect the router per the instructions in the
User’s Guide
.
4.
Once the router is connected to the modem and the PC is connected to the router, open the Web
browser. In the address field of the browser, enter the IP address of the modem. By default, that
address is 192.168.1.1. (For more in-depth instructions for configuring the router, consult
the
Linksys Etherfast Cable/DSL Router User’s Guide
.)
5.
If the PC is configured properly, the Login Screen will appear. Leave the
User
name field empty;
type the word
admin
into the password field and press the
Enter
key.
6.
Configure the router based on how the network will be configured.
•
Host Name and Domain Name
— These will only need to be assigned if the ISP requires them.
The ESI Remote IP Feature phone does not require them.
•
LAN IP address
— Leave as default.
•
WAN IP address
— Enter what the ISP has assigned.
• If the ISP has assigned
static IP addresses
to the site, enter them here. Enter at least the IP
address, the subnet mask, the default gateway, and the DNS IP addresses. Again, your ISP will
assign these to the connection. If it did not give these addresses to you, contact the ISP.
• If the ISP has assigned the connection as DHCP, click the radio button next to
Obtain an IP
address Automatically
.
7.
Click the
Apply
button.
8.
Click the
DHCP
Tab, and ensure that the
Enable
radio button is selected. If the network already has
a DHCP server running, click the
Disable
radio button.
9.
Click the
Apply
button.
10.
Restart the Router by powering if off, then on again, and reboot the PC.
11.
After the router and the PC have rebooted verify the Internet connection by performing the
PING
test as described in Appendix I.
