Hi @Ron_Sanders,

In the experience of the Roon team, the Bell Home Hub series of modem/router combos don’t Bridge to a third-party router in such a way that prevents address translation from taking place within your local network. So, if your Core is connected to your own router (the Orbi) downstream of the Bell Gigahub, you won’t be able to place the Gigahub in “Bridge” mode to prevent it from blocking port forwarding.

However, other users have successfully configured port forwarding by configuring an advanced DMZ. I have linked a post describing this process in detail - hopefully, the UX for your Gigahub is similar to the other Bell models in your region, so these steps will translate 1:1.

Bell Home Hub - How to Set Up "Bridge Mode" by (Safely) Configuring Advanced DMZ

Hi folks, I’ve run into this problem off and on with Bell over the years. The bridge mode with pppoe works ok but I recently discovered that there is a simpler way to obtain an ip with an external router. No more bridge modes needed! I have the HH4000 which has the same interface as the HH3000 and can be set-up the same way. Simply set up an Advanced DMZ for your router and have the router obtain an external IP. Here are some screenshots: Setting up the Advanced DMZ: [image] Select your rou…

It’s important to note that you should ONLY connect anything on your home network to the Orbi (downstream) router if you configure an Advanced DMZ on the Gigahub. This is because you will be removing the Gigahub network firewall entirely, and relying on the Orbi’s network security layer instead. That is perfectly safe, provided you don’t place a connected device in front of the firewall by connecting to the Gigahub’s Wi-Fi.

We’ll be here to assist, and thank you for your patience so far.

I have tried Advanced DMZ on the GigaHub but found no change. Of course, I may have done something wrong.
Would I then forward the port to the core on the Orbi?

You gotta make sure your router is requesting the IP. I put mine (Asus) in auto mode and it pulls the right external IP. Also, you may want to demand a HH4000 instead of the Gigahub. That’s what I did after many issues with the Gigahub…
