If you have NAT-PMP / UPnP enabled (and it looks like that) AND have a manual port forward rule enabled at the same time, then decide for one or the other. We have seen many routers who don’t like them to be mixed
This is the forwarding rule in my router. I’ve turned uPnP off in both my routers. The ASUS connects to the Ziggo Mediabox in my apartment which is the ISP’s Internet/TV box.
The error message shows that UPnP is off. It would not be shown if the manual port forwarding rule worked, though.
The rule in your new screenshot looks ok as such. However, it forwards the port 55002 - is this the correct port number that your ARC is configured to use? In your first screenshot at the start of the topic it was configured to use port 17760.
Just to be double-sure, you don’t have any second router or smart switch in this setup?
With the variables you’ve already eliminated, the error message in Roon → ARC you’ve shared suggests one of two possible blocks to your port forwarding:
the ports you’ve tried (17760 and 55002) are in use by other software, reserved by your ISP, or otherwise restricted on this network, even if the listed exceptions don’t include these numbers. You’ve tried setting “Block All Other Ports” to negative for inbound and outbound traffic. First, power cycle or restart your router again to make sure those settings have actually taken hold.
Then, try augmenting the port assignment up or down by 1000 a few times in both Roon and the router port forwarding rule. (55000, 56000, 57000). Let us know if that helps.
The second possibility here is that Niacom has recently added a layer of address translation to your account tier. Given your location, this is certainly a possibility, as some research suggests they only (relatively) recently added coverage in that area and may now be coping with a large volume of IP addresses that they need to manage for infrastructural purposes. While more tedious, it’s worth reaching out to Niacom to ask a) if they’re using any sort of dynamic IPv4 address assignment on your account and b) if you can request a dedicated external IP address.
We’ll be here in the meantime, please reach out with any questions.
You were both correct. I have to remove and recreate the port. The devices appear in a drop down and in that instance, I forgot and used the first one.
We apologize, but due to current limitations on the network, port forwarding is not yet available in your area of the network. As we continue to grow in service, we are working in changes that will allow customers to purchase static IPs at affordable prices thus allowing for a better port forwarding experience. Currently we are still in the planning engineering stages and port forwarding is not available in your area at this time. We apologize for any inconvenience. Please check in with us again in the future to see if we have been able to implement the features discussed and feel free to reply with any questions.
