Simple LAN WDS configuration
Objective
Connect 3 LAN using 2 GW2347 and 1 GW2348 and they will be transparent for the diferent Ethernet subnets.
GW2347_0 - - - - - GW2348 - - - - - - GW2347_1 | | | LAN LAN LAN
Will support Spaning tree protocol to alow the case when GW2347's were in the same Ethernet segment. This case:
GW2347_0 - - - - - GW2348 | | GW2347_1 - - - - - - -
Definitions
The 3 LAN's are in the same IP subnet 10.1.1.0/24 (for example).
The GW234x management IP will be in 192.168.5.0/24 (for example).
All the GW234x has Winstron CM9 miniPCI cards into them.
Names of GW234x devices will be:
acbr51 with 192.168.2.51 for the GW2347_0
acbr52 with 192.168.2.52 for the GW2348
acbr53 with 192.168.2.53 for the GW2347_1
Prerequisites
All GW234x devices are with factory defaults configuration (all has their nvram erased using RedBoot commands).
All GW234x devices has DDWRT V24 pre - RC 7 (20080317) (or newer) flashed.
Configuring the devices
I only coment the parameters I changed or if the parameter value is important for our purpose.
IP Parameters
Setup->Basic Setup page
Section WAN:
- Connection Type: Disabled
- STP: Enabled
Section Optional Settings:
- Router and Hostnames: acbr51, acbr52, acbr53 (each name with each device).
- Domain Name: mydomain (put yours here if you want).
Section Router IP:
- Local IP Address: 192.168.2.51, 192.168.2.52, 192.168.2.53 (each IP with each device)
- Subnet Mask: 255.255.255.0
- Gateway: 192.168.2.254 (leave in blank if you don't use)
- Local DNS: 192.168.2.254 (leave in blank if you don't use)
Section DHCP:
- DHCP Server: Disable (Enable and configure if you want, I don't use it here).
Section Time Settings:
- Time Server: 192.168.2.254 (leave in blank if you don't use)
WiFi Parameters
Wireless -> Basic Settings page
In each interface I thanged this parameters:
- Regulatory Domain: SPAIN (I'm in Spain).
- Wireless Mode: AP (Will be a simple WDS).
- Wireless Network Mode: A-Only (There are many home networks in 2,4GHz).
- Turbo Mode: Enabled (Is not required, but I like it).
- Outdoor Band: Enabled or Disabled. This allow you to select the indoor channels or the outdoor ones.
- Wireless Network Name (SSID): myssid (I use the same in all interfaces).
- Wireless Channel: 50-Indoor-Turbo for acbr51-acbr52 link and 130-Outdoor-Turbo for acbr52-acbr53 link.
The configuration will be:
CH50 CH130 acbr51 (ath0) - - - - - (ath0) acbr52 (ath1) - - - - - - (ath0) acbr53
NOTES:
- With AP mode works fine the WDS disabling Turbo Mode'. You must wait a bit to see the comunication, but it works fine.
- With AP mode works fine the WDS enabling Turbo Mode'. You must wait a bit to see the comunication, but it works fine.
Wireless -> Wireless Security page
I allways use WPA-PSK with AES with a large phrase. I'll don't change it now for a simple link.
For each interface in each device I use:
- Security Mode: WPA-Personal
- WPA Algorithms: AES
- WPA Shared Key: AvErYlOnGpHrAsE (use a long key here).
Please, be sense in I use me own configuration, you can use this configuration too, but this is only an example of working configuration.
WDS Parameters
Wireless -> WDS page
For acbr51 (1 atheros only):
- First column: LAN
- Second column: the ethernet mac of acbr52 ath0 interface.
- Third column: acbr52
For acbr52 (2 atheros):
- First column: LAN in first row and LAN into second row.
- Second column: the ethernet mac of acbr51 ath0 interface in the first row and acbr53 ath0 MAC into second row.
- Third column: acbr51 into first row and acbr53 into the second row.
For acbr53 (1 atheros only):
- First column: LAN
- Second column: the ethernet mac of acbr52 ath1 interface.
- Third column: acbr52
You must remenber this:
CH50 CH130 acbr51 (ath0) - - - - - (ath0) acbr52 (ath1) - - - - - - (ath0) acbr53
