Hi everyone,
I need some help with an issue I’m encountering with my Fortigate setup.
Setup Details:
- Router: ZTE (configured in bridge mode)
- Firewall: Fortigate
Issue:
Despite successfully configuring the ZTE router in bridge mode and connecting it to my Fortigate, the Fortigate is still receiving an internal IP address instead of a public IP. Additionally, my DDNS is only working within my local network. When I try to access it from outside over the internet, it doesn’t work.
Steps I’ve Taken:
1. Configured Bridge Mode:Verified that the ZTE router is set to bridge mode.
2. Fortigate WAN Interface: Configured the Fortigate WAN interface to obtain an IP address automatically via DHCP.
3. MAC Address Cloning: Ensured the MAC address of the Fortigate is registered with my ISP (if required).
4. Release and Renew IP: Attempted to release and renew the DHCP lease on the Fortigate WAN interface.
5. Restarted Devices: Power cycled both the ZTE router and the Fortigate.
Despite these steps, the Fortigate continues to receive an internal IP address. This internal IP address is causing issues with DDNS, which only works on the local network but not from external connections.
Questions:
1. Is there any additional configuration needed on the Fortigate to ensure it gets a public IP address?
2. Could there be specific settings on the ZTE router that need adjustment beyond bridge mode?
3. Any suggestions on why DDNS would only work within my local network and not from the internet?

I think it's time to call in your ISP's support. If you still have some doubt about FGT, you can just hookup your laptop or desktop machine directly to the router to see if it's any different.
