: Ensure you select which LAN port on the ZTE will send the bridged signal to your external router. ⚠️ A Few Real-World Caveats Zte F689 Bridge Mode

This is the biggest reason. When you connect a second router to a router that is already performing NAT, you create a "double NAT" scenario.

Bridge mode ensures only your personal router handles NAT, avoiding this problem entirely.

Ensure the option remains enabled and contains the exact VLAN ID you noted in Step 2. Click Modify or Save . Option B: Creating a New Bridge Profile
