 +The secondary (station) router is unbridged in a different subnet (with NAT), while a [[Client_Bridge|Station Bridge]] or [[Client_Bridged|Station Bridge (Routed)]] is the same subnet as the host.
-=Introduction=+==Introduction==
-This wireless mode allows a router to connect to a remote router as a client. This mode creates 2 separate subnets. Since the computers within the different subnets cannot see each other directly, this requires the enabling of NAT between the wireless and the wired ports, and setting up port forwarding for the computers behind the local wireless device. Segments connected via Client Mode Wireless cannot share a DHCP server.+This mode is NOT for WIRED connections between two routers, like an Access Point. It is a wireless connection between two routers only, usually to the primary gateway router. A Station Mode router connects to a Wireless Access Point (WAP) wireless connection as the WAN interface, and shares the internet connection only to the LAN ports, or a separate WAP for multi-radio routers. It is not seen as a WAP, nor accepts wireless connections by other client devices.
-If you have a wireless router connected to the Internet in a location and would like to connect wired clients in a remote location to allow shared Internet, one solution is to use [[Client Mode Wireless]]. This requires the remote router is a WRT54G running DD-WRT (or similar firmware). The WRT running client mode will connect to the main router as though it were any other computer, and will share the connection as though the main router were connected directly to its WAN port. This means that both routers will be on seperate subnets--and thus the clients will all be on seperate subnets), and NAT will exist between the routers so port forwarding will need to be done at both routers, not just the main router.+The primary (host) router is not required to be running DD-WRT firmware. The primary and secondary (Station Mode) routers must be on separate subnets, and NAT is used between them. Thus, when port forwarding is needed it must be configured at both routers - not just on the host router.
 +
 +A Station Mode router uses its own DHCP server for IP Address, Gateway, and DNS server to connected devices. To have computers connected to both routers (main and secondary) and co-exist in the same subnet, set up DD-WRT as a [[Client_Bridge|Station Bridge]](Broadcom), [[Client_Bridged|Station Bridge (Routed)]], [[Repeater Bridge]], or use [[WDS_Linked_router_network|WDS]]. Further explanation of bridging modes is at [[Linking_Routers|Linking Routers]].

-Si tienes un router conectado a Internet en 1 localización y te gustaria conectar varios clientes en una localización remota y permitir el acceso a Internet, la solución ideal es usar el modo Cliente del Linksys WRT54G. Se necesita un WRT54G en el sitio remoto corriendo nuestro firmware DD-WRT o alguno similar. El modo cliente recoge la señal wireless a traves del pueto WAN (internet) y es compartida por los 4 puertos de la LAN. Ademas se pueden separar la 4 bocas en 4 VLANS diferentes. Con este tipo de configuración se consigue mayor velocidad en las conexiones que con WDS, ademas de que la red remota queda invisible para la red inalambrica, a no ser que se configuren las rutas para que no lo sea. Con esta configuración solo consumiremos una dirección IP de la red inalambrica y en nuestra red local podremos tener todos los ordenadores que queramos conectados por cable. Para que nos hagamos una idea, funciona igual que un router ADSL conectado a Internet, en el que el cable del telefono se conecta a la boca WAN i es por donde nos entra Internet, y en el resto de bocas tenemos nuestra red privada que encamina todas las salidas a Internet por el cable telefonico. Al igual que los routers ADSL, hay que abrir los puertos para los diferentes servicios que queramos sean accesibles desde la red Wireless.+To allow internet access but prevent ''192.168.1.x'' clients from seeing each other on ''br0'', use this firewall script (iptables):

The secondary (station) router is unbridged in a different subnet (with NAT), while a Station Bridge or Station Bridge (Routed) is the same subnet as the host.

Contents

[edit] Introduction

This mode is NOT for WIRED connections between two routers, like an Access Point. It is a wireless connection between two routers only, usually to the primary gateway router. A Station Mode router connects to a Wireless Access Point (WAP) wireless connection as the WAN interface, and shares the internet connection only to the LAN ports, or a separate WAP for multi-radio routers. It is not seen as a WAP, nor accepts wireless connections by other client devices.

The primary (host) router is not required to be running DD-WRT firmware. The primary and secondary (Station Mode) routers must be on separate subnets, and NAT is used between them. Thus, when port forwarding is needed it must be configured at both routers - not just on the host router.

A Station Mode router uses its own DHCP server for IP Address, Gateway, and DNS server to connected devices. To have computers connected to both routers (main and secondary) and co-exist in the same subnet, set up DD-WRT as a Station Bridge(Broadcom), Station Bridge (Routed), Repeater Bridge, or use WDS. Further explanation of bridging modes is at Linking Routers.

  • If using a multi-band router, do not set more than one band to CB. The other radio(s) would normally be set as AP. For example, the 2.4GHz radio can a CB while the 5GHz is an AP, or vice versa.

[edit] Station Mode Setup

The secondary station router will be on a different subnet than the primary host router. For example, if the host router IP address is 192.168.1.1, configure the station router to 192.168.2.1.

  1. These instructions assume a reset router. Broadcom routers: read the Peacock thread
  2. Connect a cable from your computer to the LAN port on your router.
  3. (Optional) Set your computer to a static IP address (e.g. 192.168.1.7, subnet 255.255.255.0)
  4. Connect to the DD-WRT GUI at 192.168.1.1 in a browser
  5. Set a username and password - if not asked for this, do a proper reset!
  6. Go to Wireless: these settings must match the primary host router - Check spelling and case!
    • In Wireless->Basic Settings and change the Wireless Mode to "Station"
    • Set the Wireless Network Name (SSID) to exactly match the primary router. Click Save (not Apply)
      • If multiple routers broadcast the same SSID, to connect to a specific one (i.e. the primary router, instead of a repeater), enable MAC Filtering on the Wireless Tab, and add the specific device's MAC Address.
      • MAC Address can be found on the "Site Survey" page, linked from the Wireless tab in Status
    • Wireless Security: set the Security Mode and other information same as primary router. Click Save (not Apply)
  7. (Optional) If available, in Wireless tab (or under Advanced), set (or disable) the Ack Timing in meters
  8. Go to Setup->Basic Setup: if needed, change Connection Type to Static IP from "Automatic Configuration - DHCP"
    • Static IP allows easier access remote GUI, SSH, or telnet access is enabled under Administration
    • If the station router requires external management, go to Setup->Basic Setup, set the WAN port protocol as needed and enter info provided by your ISP. This is the setting that is bonded to the wireless interface.
  9. In Network Setup set the Local IP Address to a different subnet from the primary host router (e.g. 192.168.2.1)
  10. Set the Gateway address to the primary host router gateway or internet will not work (e.g. 192.168.1.1)
    • The device should be in GATEWAY Advanced Routing mode, not ROUTER, or Masquerade/NAT does not happen.
  11. (Optional) Set your local DNS to the IP address of your station router
  12. (Optional) Set Static DNS servers in Network Address Server Settings (DHCP) if not provided or wanted from WAN
  13. (Recommended) Change the Time Zone and DST settings as needed.
  14. (Optional) Set a "Server IP/Name" in Time Setting section for NTP (blank uses a default server)
  15. Click Save (not Apply)
  16. (Optional) In Security->Firewall, disable SPI Firewall if security between AP & Station is not needed
  17. Click Apply, then change the computer back to auto IP/DNS if needed (replug the LAN cable if not working)
  18. Let the station router reboot and connect to the host, then configure on the new Station IP address as needed
  19. If not working, unplug the router for 30sec and retry

[edit] Station Mode Restrictions

To allow internet access but prevent 192.168.1.x clients from seeing each other on br0, use this firewall script (iptables):

iptables -I FORWARD -i br0 -d 192.168.1.0/24 -j DROP

[edit] Troubleshooting

If the preceding instructions do not work, it is usually an encryption or password problem. Disable encryption on the primary router and retry the setup. Using proper encryption and the correct case-sensitive password is key. Do a reset and start over. Note: WPA2-AES (aka CCMP) is required for 802.11N (and newer) devices.
