Configuration Scenarios

21.2.11 Remote Wireless Router-to-Central Wireless Router

Figure 21-9 Remote Wireless Router-to-Central Wireless Router

Step 1.

Set the

Central Wireless Router/Bridge

to run as a

Central Wireless Router

; see

section

21.2.3

(wireless Interface IP is 192.168.1.1, Ethernet Interface IP is 192.168.2.1, 192.168.2.254

is the factory default.

Step 2.

Set wireless parameters on

Central Wireless Router

Channel

and

SSID

Step 3.

Set the

Remote Wireless Router/Bridge

as a

Remote Wireless Router

; see

section 21.2.7

(Wireless Interface IP is 192.168.1.2, Ethernet Interface IP is 192.168.10.1, 192.168.1.1 is the
factory default.

Step 4.

Set wireless parameters on

Remote Wireless Router

Channel

and

SSID

, these parameters

must be the same as the

Central Wireless Router

Step 5.

Set the DHCP server service on the

Remote Wireless Router

and apply it to the Ethernet

Interface.

Step 6.

The

Remote Wireless Router

assigns IP address to PC1 and PC2.

You can turn

‘off’ NAT (PAT)

on the

Central Wireless Router

and turn ‘

on’

NAT (PAT)

on the

Remote

Wireless Router

. Any outgoing packets will be translated to address 192.168.1.2.

Central Wireless Router

: turn

‘off’
