To use an OpenWrt router as your home gateway, connect its WAN port to your modem or existing router, connect household devices to its LAN or Wi-Fi, and keep the WAN and LAN on different IP subnets. In the usual router configuration, OpenWrt’s firewall and DHCP server stay enabled. The exact WAN protocol and any ISP login or VLAN settings depend on your provider and upstream equipment.
Choose how OpenWrt will connect to the internet
First decide whether OpenWrt will sit behind your existing ISP router or replace it. The easiest starting arrangement is usually to leave the ISP router in place and connect OpenWrt’s WAN port to an unused LAN port on it. OpenWrt then acts as a separate gateway for the devices connected to its LAN and Wi-Fi. This arrangement normally creates double NAT: both routers translate network addresses.

Double NAT is generally compatible with ordinary web browsing, but it can complicate inbound connections, such as hosting a server, and some peer-to-peer online games. If that matters, check whether the ISP device supports bridge mode or an exposed-host arrangement. The available options and their setup vary by device and service. OpenWrt’s guide to router, gateway and NAT configurations explains the trade-offs.

If OpenWrt will connect directly to a modem or replace the ISP gateway, do not assume the WAN uses DHCP. A provider may require a different WAN protocol, authentication, or VLAN configuration. Check the ISP’s instructions and the OpenWrt guide for your specific hardware; the available documentation does not establish a universal ISP configuration. OpenWrt as a router device describes the standard router arrangement and its defaults.

Prepare the router and connect to its management interface
- Confirm support for your exact device. Check the model and hardware revision against the current OpenWrt device instructions, and follow those instructions to select and install the correct image. Port layouts and mappings vary, so do not choose firmware based on a similar-looking model.
- Connect a computer to a LAN port. Use the initial access method documented for your device to open its management interface. Keep the computer connected to LAN while you configure the router.
- Check the upstream network’s address range. If an existing router uses the same subnet you plan to use on OpenWrt’s LAN, change OpenWrt’s LAN address so the ranges do not overlap. OpenWrt’s documented example is to use
192.168.2.1for OpenWrt when the upstream network uses192.168.1.0/24. - Record the new management address. Applying a LAN address change may move the management interface to that new address and interrupt the current session. Reconnect to the interface at the new address before continuing.
Exact menu labels vary by release and device. Use the current instructions for your model rather than relying on a menu path written for a different installation. OpenWrt’s documentation index links to its setup documentation.

Connect the WAN and keep the gateway services enabled
- Connect the upstream cable. For a cascaded setup, plug one end into OpenWrt’s WAN port and the other into an unused LAN port on the ISP router. If connecting directly to a modem, use the modem connection specified by your ISP and device instructions.
- Use the correct WAN protocol. When another router supplies addresses, DHCP is the ordinary default. For a direct ISP connection, use the protocol and any authentication or VLAN settings required by that provider.
- Leave firewall and DHCP enabled for normal router mode. These are enabled in the ordinary OpenWrt router configuration. DHCP supplies addresses to downstream clients; the firewall helps separate and protect the LAN from the WAN.
- Configure Wi-Fi separately. Set up wireless access for the installed release and radio hardware, then test a device over Wi-Fi as well as one connected by Ethernet.
Check the network before troubleshooting further
- LAN: A client connected to OpenWrt should receive an address in the OpenWrt LAN range and be able to reach the router’s management interface.
- WAN: Check whether OpenWrt has a WAN address. In a cascaded setup, this should ordinarily be supplied by the upstream router when WAN is configured as a DHCP client.
- Address ranges: Confirm that the WAN-side and LAN-side networks do not overlap. If they do, change the OpenWrt LAN subnet.
- Client tests: Try internet access from both a wired client and a wireless client. If one works but the other does not, focus on that connection rather than changing the WAN configuration.
If OpenWrt has no internet
- Check the WAN cable and port. Make sure the cable runs from OpenWrt’s WAN port to the modem or upstream router’s internet-facing device. For the cascaded arrangement, the other end belongs in an unused LAN port on the ISP router.
- Inspect LAN and WAN addresses. If their network ranges overlap, change the OpenWrt LAN address to a distinct subnet and reconnect to the management interface using its new address.
- If WAN has no address, check upstream settings. Verify the upstream router or modem is working, then confirm the ISP-required WAN protocol, authentication, and any VLAN configuration. Randomly changing LAN DHCP or firewall settings will not supply a missing WAN address.
- Consult the connectivity guide for further checks. OpenWrt’s Troubleshooting Internet Connectivity guide covers additional diagnostics.
