When setting up a network, it may be necessary to configure a router behind a router to extend network coverage or create a separate network segment. However, configuring a router behind a router can be tricky if not done correctly, and may result in connectivity issues or other problems. In this guide, we will outline the steps needed to properly configure a router behind a router and provide some tips to help ensure a successful setup.

How to Configure a Router Behind A Router
Configuring a router behind a router requires some additional steps to ensure proper communication between the two devices. Follow these steps to configure a router behind a router:
- Determine the IP address range of the main router’s LAN. You can find this information by checking the DHCP settings of the main router or by looking at the IP address of a device connected to it.
- Connect the WAN port of the secondary router to an available LAN port of the main router using an Ethernet cable.
- Access the web interface of the secondary router and configure its WAN settings to obtain an IP address automatically through DHCP. This will ensure that the secondary router can communicate with the main router.
- Configure the LAN settings of the secondary router to use a different IP address range than the main router. For example, if the main router uses the IP address range 192.168.1.x, you could configure the secondary router to use the range 192.168.2.x.
- Disable the DHCP server on the secondary router. This is important to prevent conflicts between the two routers.
- Configure any additional settings, such as port forwarding or firewall rules, on the secondary router as needed.
By following these steps, you can configure a router behind a router and ensure that both devices can communicate with each other and with devices on the network.
In addition to the steps outlined above, here are some additional tips to keep in mind when configuring a router behind a router:
- Use different SSIDs for each router’s wireless network to prevent interference and ensure proper device connectivity.
- Consider using a static IP address for the secondary router’s LAN interface to make it easier to manage and access.
- Check for firmware updates for both routers and make sure they are running the latest version to ensure optimal performance and security.
- If you experience connectivity issues, check the routing table of each router to ensure that they are properly configured to communicate with each other and with devices on the network.
- Be aware that configuring a router behind a router can result in a “double NAT” situation, which may cause issues with certain applications or services that require direct access to the internet. To avoid this, consider setting up the secondary router in “bridge mode” or using it as an access point instead of a router.
By following these additional tips, you can ensure that your router behind a router configuration is set up correctly and running smoothly.
Conclusion
Configuring a router behind a router can be a challenging task, but by following the steps outlined above and keeping some additional tips in mind, you can ensure a successful setup. It is important to properly configure the IP addresses and subnet masks of both routers, set up proper NAT and port forwarding rules, and configure the wireless settings to avoid interference or connectivity issues. By taking the time to properly configure your router behind a router setup, you can create a more efficient and effective network for your home or business.
