The scheme depicts two RUTxxx routers - RUT1 and RUT2. RUT1 has access to the Internet through an undefined type of WAN (it can be any). RUT2 acts as a WiFi Station (STA) and gains access to the Internet via RUT1's WiFi Access Point (AP) (SSID: RUT_WiFi). RUT2's DHCP Server is disabled. This is done so that the end devices connected to RUT2 get IP addresses from RUT1's DHCP Server with the help of Relayd.

A WiFi Access Point (AP) and DHCP Server are enabled by default on RUTxxx routers, but if you wish to make changes, you can find the configuration pages for these services by logging in to the router's WebUI and visiting the '''Network → Wireless''' section for WiFi and '''Network → Interfaces''' for DHCP.

The key things you need to configure in RUT2 are:

The key things you need to configure in RUT2 are:

* Enable WiFi WAN and connect to RUT1's WiFi Access Point

* Enable WiFi WAN and connect to RUT1's WiFi Access Point

* Enable Relayd and disable DHCP Server

* Enable Relayd and disable DHCP Server

'''NOTE''': in this case, the steps should be taken in the order they are presented, because if you disable RUT2's DHCP Server first, you may lose access to your router. So let's begin by setting up WiFi WAN.

* To set up WiFi WAN, login to the router's WebUI and navigate to the Wireless section found under the Network tab ('''Network → Wireless'''):

* Set up WiFi WAN via WebUI by navigating to the '''Network → Wireless → SSIDs''':

* Press the button Scan:

* Click the '''Scan 2.4Ghz''' button:

* Once the scan is complete, you will be presented with a list of nearby WiFi Access Points. Locate and choose RUT1's Access Point and click "Join network":

After this, you will get a new window in which you will have to type your RUT1 WIFI password and create the Interface's name.

* Configuration for both DHCP and Relayd takes place in the Interfaces section of the router's WebUI. Log in and navigate to the Interfaces section which is located under the Network tab ('''Network → Interfaces'''):

* Configuration for Relayd takes place in the Relayd section of the router's WebUI by navigating to the '''Network → Wireless → Relayd''':

----

----

* In the LAN page set DHCP to "Disable":

* In the Relayd section, set '''Enabled''' toggle to '''On''', set '''Interface''' option to '''lan''', set '''Wireless interface''' option to '''wifi1''', and click '''Save & Apply''' button:

* Place a check mark next to the "Enable relayd" field and click the "Save" button:

* Disable the DHCP server on the LAN interface section and click '''Save & Apply''' button:

==Testing the set up==

==Testing the set up==

If you've taken all of the steps described above, the configuration is done. But as with any other configuration, it is always wise to test the set up in order to make sure that it works properly. To test this particular set up, login to any of the routers go to '''Services → CLI'''. Login with user name: '''root''' and the router's admin password. You should then be able to '''ping''' the other router or any of the end devices that you have connected to either of the two router's. To execute a ping command, type '''ping <devices_ip>''' into the console and press the Enter key:

Replace <devices_ip> with an actual IP address of a device that is in your network and if the ping requests are successful it means the configuration is working. You can check the IP addresses of the devices connected to your network in RUT1's '''Status → Network → LAN''' section.

An important issue to bring up is that the two routers will not be able to communicate with each other via their LAN IPs if they have LAN IP addresses in different subnets. If that is the case, there are still a few options you can take without changing either of the routers IP addresses:

An important issue to bring up is that the two routers will not be able to communicate with each other via their LAN IPs if they have LAN IP addresses in different subnets. If that is the case, there are still a few options you can take without changing either of the routers IP addresses:

* When communicating between routers, use RUT2's WAN IP instead of its LAN IP. This will work because RUT1 will lease the WAN IP address to RUT2 from its LAN network. If that is the case you chose, then don't forget to check RUT2's WAN IP after completing the '''[[Relayd#WiFi_WAN|3.2.1]]''' step of this guide

* Add Static Routes to each router in the '''Network → Routing → Static Routes''' section. This must be done from both ends, i.e., you must configure a route both in RUT1 and in RUT2
