Hi @Bengt_Sederlin,

Welcome to the forum.

I think a manual port forwarding rule will solve your issue.

I couldn’t found a youtube video of your router model, but found a manual (here).

First in the Roon App go to Settings → Roon Arc and write down the ip address and port number.

Then see page 67 in the manual.
Under private ip enter the ip address you wrote down.
Under private and public port enter the port number you wrote down.
Under protocol select TCP**
Then click Apply.

Hope it helps.

Maarten.
