Just upgradet my network to Nest Wifi Pro, and now I can not get external access to the NAS, or any of the applications running og the NAS. I tried port forwarding som of the ports i the Google Home App, but still no external accsess. 

The setup i basic, with a broadband router in av bridge-mode, GNWP is functioning as the router. 

Any ideas?

Hi LTgriM,

 

It's understandable that you're facing external access issues with your NAS after upgrading to Google Nest Wifi Pro. Here are some potential reasons and troubleshooting steps to help you regain access:

 

Potential Causes:

  • Incorrect Port Forwarding: Double-check your port forwarding settings in the Google Home app. Ensure you've entered the correct internal and external ports, protocol (TCP/UDP), and assigned the appropriate device (your NAS) for the forwarded ports.
  • Firewall Rules: Verify that the Google Nest Wifi Pro firewall isn't blocking incoming traffic on the forwarded ports. You might need to create specific firewall rules to allow access for the ports you're forwarding.
  • Double NAT: If your broadband router is in bridge mode, it shouldn't be performing NAT (Network Address Translation). However, ensure your ISP isn't also implementing NAT on their end, which could create conflicts.
  • NAS Configuration: Check your NAS settings to ensure it's configured to allow remote access and that the firewall on the NAS itself isn't blocking access.

 

Troubleshooting Steps:

 

Verify Port Forwarding:

  • Double-check the internal and external ports, protocol, and device selection in your Google Home app settings for port forwarding.
  • Try temporarily disabling the firewall on your Google Nest Wifi Pro to see if it resolves the issue. Remember to re-enable it afterward for security.

 

Check Double NAT:

  • Contact your ISP to confirm if they are performing NAT on their network. If so, you might need to request a public IP address or bridge their modem/router as well.

 

Review NAS Configuration:

  • Consult your NAS manual or online resources to ensure remote access is enabled and any firewall settings on the NAS aren't blocking access.

 

Advanced Troubleshooting:

  • If the above steps don't work, consider:
    • UPnP: If your NAS supports UPnP (Universal Plug and Play), enable it on your Google Nest Wifi Pro. This might automatically configure port forwarding for your NAS.
    • Static IP: Assign a static IP address within your local network to your NAS for better stability and easier port forwarding management.
    • Try using the ISPś DNS settings.

 

Note: Refer to the official documentation for your specific NAS model for detailed instructions on remote access configuration.

Let us know how it goes.

 

Best,

Dan
