Enabling bridge mode delivers significant performance improvements:
The bridge mode feature allows the device to function exclusively as a modem, passing the public IP address directly to an external router . However, this feature is frequently restricted or hidden by ISPs like Claro through firmware locks or JavaScript scripts that disable the "Apply" button. Key Features of Bridge Mode
Managing advanced features like Quality of Service (QoS), custom DNS routing, VLAN tagging, and advanced firewall rules is vastly easier on a dedicated third-party router (such as Asus, Netgear, or a custom pfSense/OPNsense box). Prerequisites Before Configuration
If the "Route" dropdown cannot be changed, some users use the Inspect Element trick in their browser to manually enable the hidden selection. Are you seeing a specific error message or is the option to change the connection type in your menu? Converge F670L Bridge mode - Github-Gist zte f689 bridge mode exclusive
Select PPPoE as the connection type and input the ISP username and password you gathered earlier. If your ISP uses DHCP: Select Automatic IP / Dynamic IP .
Manually configure a static IP on your computer's network adapter (e.g., IP: 192.168.1.50 , Subnet Mask: 255.255.255.0 , Gateway: 192.168.1.1 ). Enter 192.168.1.1 into your browser to manage the device.
Consumer-grade ISP gateways often have limited RAM and weak processors. Shifting the routing, DHCP, and firewall responsibilities to a dedicated third-party router frees up the ZTE F689 to focus solely on fiber-to-copper conversion. If your ISP uses DHCP: Select Automatic IP / Dynamic IP
Open a web browser and type 192.168.1.1 (or 192.168.0.1 ) into the address bar. Enter your administrator username and password. Step 3: Delete or Modify the Existing WAN Connection Navigate to the top menu and click on . Select WAN from the left-hand sidebar.
Connect your computer directly to one of the LAN ports on the ZTE F689 using an Ethernet cable.
Turn off both the and 5 GHz wireless RF bands. Click Apply . Navigate to Local Network > LAN > DHCP Server . and network management.
Note down the VLAN ID (often something like 881 or 10 ). Create a New Item: Select Create New Item . Set Type to Bridge Connection . Enter the VLAN ID you noted earlier. Bind the connection to a specific LAN port (e.g., LAN1).
This is normal behavior because DHCP is turned off on the ZTE unit. To log back into the ZTE F689 in the future, assign a static IP address to your computer’s network card manually (e.g., Set IP to 192.168.1.50 , Subnet Mask to 255.255.255.0 , and Gateway to 192.168.1.1 ). Connect your computer directly back into LAN Port 2 of the ZTE F689 to access the page. Issue 3: The Settings Reset Automatically
In the menu, you can either modify the existing profile or create a new one.
Bridge mode allows you to keep your ISP's ONT/router in place (required for authentication and TV/phone services) while letting your personal router handle everything else. It eliminates double NAT issues, passes the public IP directly to your router, and gives you full control over port forwarding, firewall rules, and network management.
