Set up AP 2 and AP 3 to be wireless repeaters.
a.
In the Wireless Repeating Function screen for AP 2 and AP 3, select the
Enable
Wireless Repeating Function
check box.
b.
Select the
Wireless Repeater
radio button.
c.
Select the corresponding
Disable Wireless Client Association
check box.
d.
Enter the MAC addresses for your modem router in the Base Station MAC Address
field.
e.
Click
Apply
.
3.
Disable the DHCP server on AP 2 and AP 3. AP 1 will then be the DHCP server.
4.
Verify the following for all access points:
The modem router and other access points operate in the same LAN network address
range as the LAN devices.
Only one access point, your modem router in
Figure
15
, is set up as the base station.
The others are set up as repeaters.
All access points, including your modem router, are on the same LAN. That is, all the
access point LAN IP addresses are in the same network.
If you are using DHCP, all access points should be set as DHCP clients. This setting
is
Obtain an IP address automatically (DHCP Client)
in the Basic Settings screen.
All access points, including your modem router, use the same SSID, channel,
authentication mode, if any, and WEP security settings if security is in use.
5.
Verify connectivity across the LANs. A computer on any LAN segment should be able to
connect to the Internet or share files and printers with any other PCs or servers connected
to any of the three LAN segments.
Note:
Wireless stations configured as in
Figure
14
on page
89 cannot
connect to the modem router or access points. If you want wireless
stations to access any LAN segment, use additional access points in
in any LAN segment.
Repeater with Wireless Client Association
In the repeater mode with wireless client association, your modem router sends all traffic to a
base station access point. You can set up the modem router as either the base station
(parent) or as the repeater (child) access point.
Note that the following restrictions apply:
You
do not
have the option of disabling client associations with this modem router.
You cannot configure a sequence of parent-child APs. You are limited to only one parent
access point, although if your modem router is the parent access point, it can connect
with up to four child access points.

Virtual Private Networking
This chapter describes how to use the virtual private networking (VPN) features of the modem
router. VPN communications paths are called tunnels. VPN tunnels provide secure, encrypted
communications between your local network and a remote network or computer. See
Appendix
B, NETGEAR VPN Configuration
, and click the link to
Virtual Private Networking (VPN)
on
page

Overview of VPN Configuration
Two common scenarios for VPN tunnels are between a remote PC and a network gateway;
and between two or more network gateways. The DGN2200 supports both types. The
DGN2200 supports up to five concurrent tunnels.
Client-to-Gateway VPN Tunnels
Client-to-gateway VPN tunnels provide secure access from a remote PC, such as a
telecommuter connecting to an office network.

A VPN client access allows a remote PC to connect to your network from any location on the
Internet. The remote PC is one tunnel endpoint, running the VPN client software. The modem
router on your network is the other tunnel endpoint. (See
Set Up a Client-to-Gateway VPN
Configuration
on page
98.)
Gateway-to-Gateway VPN Tunnels
Gateway-to-gateway VPN tunnels provide secure access between networks, such as a
branch or home office and a main office.
