Great to hear, @crummwoody.
It looks like port forwarding didn’t automatically configure with your Orbi network; we’ll need to enable port forwarding for cellular data use of ARC.
The port forwarding error diagnostic you shared suggests that the router can see NAT-PMP enabled, but there’s an issue with the Core reaching the broader internet. Not to worry - this is a simple and (usually) easily resolvable issue, likely arising from some settings in the Orbi router.
A few things to check from here to enable port forwarding:
- Do you have a modem/router in your setup in addition to the Orbi router? Usually, the error you’ve reported is due to a second routing providing redundant network address translation (NAT), which prevents Roon from reading your routable IP address accurately.
- If you have only one router in your setup, please see this post: ARC Not Connecting (ORBI Mesh). I recommend you try enabling Bridge mode on the Orbi router web administration page.
- If you above steps don’t work, please let us know your internet service provider. We want to rule out that there is carrier-grade NAT at the level of the ISP blocking the port, as this might require you to contact them and request some settings changes to your account.
We have a list of solutions for known issues with routers, ISPs, and other difficulties encountered by ARC users in the support section here: https://community.roonlabs.com/t/routers-and-isps/203656
We’ll proceed from there and the team will be watching for your response.
