Wanderlust World Wanderlust World Your ADSL router can operate in two fundamentally different modes. Choosing the right one determines whether the device acts as a simple modem or as the brain of your home network.
In bridge mode, the router does not route. It terminates the ADSL line, authenticates with your ISP (via PPPoE, DHCP, or static IP), and passes the raw internet connection—public IP and all—to a single device plugged into its LAN port (usually your own router).
Use when: You have a superior standalone router (mesh system, enterprise gear, custom Linux box) and want zero double-NAT, full feature control, and clean troubleshooting.
This is the default. The device authenticates the WAN link and runs a full LAN stack:
Use when: You want plug-and-play, have no separate router, or prefer one box to manage.
| Feature | Bridge Mode | Router Mode |
|---|---|---|
| Internet Connection | Passes through (modem only) | Establishes & manages |
| IP Assignment | None (upstream device gets public IP) | Assigns private IPs via DHCP |
| Routing/NAT | Disabled | Enabled |
| Firewall/Wi-Fi | Absent | Built-in |
| Typical Setup | ISP → ADSL Router (bridge) → Your Router → Devices | ISP → ADSL Router (router) → Devices |
If you leave the ISP box in router mode and plug your own router into it, you get two NAT layers. This breaks port forwarding, VPNs, gaming, and VoIP. Bridge mode on the ISP box (or DMZ/IP passthrough) eliminates this.
Log into the ADSL router's web UI (usually 192.168.1.1), find "Operation Mode," "WAN Mode," or "Bridge/Router," select Bridge, save, reboot. Your own router must then handle PPPoE login (enter ISP username/password).
For most homes, router mode is fine. For enthusiasts, power users, or anyone with a mesh system—bridge mode unlocks your gear's full potential.
