Description of Issue
Can’t get ARC to work. I have a multiple NAT situation. This has been solved by defining port forwarding on both of the routers and Plex is working perfectly like this. Unfortunately, I couldn’t get Roon Arc to work with a similar configuration to Plex.
The IP of the tplink router on the netmaster network is 192.168.1.12
The IP of the Roon server on the tplink is 192.168.0.100 (not static but reserved to connect always to the same ip)
I tried ports 50000 and 20000 and the result is the same.
As stated before, the same config works with Plex albeit from a QNAP Nas.
Thank you for your report and for your patience here while your case reached the queue. It is certainly strange that it is working for Plex just fine but not for Roon this way.
Did you reboot the routers after making these settings? What happens if you try to connect ARC to the ISP router directly, does the port forwarding work in that case?
It is a bit challenging physically as they are in different rooms and the roon server in a hidden cupboard but I will find time to try and report back.
If i am correct you configured a port forwarding for Roon Arc to port 55002? I read some where on this forum that some ISP’s don’t “want” you to use certain port numbers.
Could you change in the Roon App under Settings → Roon ARC the port number in ie. 44135 and see if that works?
Your router configuration is showing two different subnets, 192.168.1.xxx and 192.168.0.yyy. Roon has to work on the same subnet (all having similar 192.168.aaa.bbb IP addresses in your case). Based on how you describe your network configuration, Roon should be on a 192.168.1.xxx address to match that of the TP-Link router.
Can you place your Netmaster device in Bridge mode, or alternately set the TP-Link router in bridge mode, and have port forwarding active on the device that remains the router?
Did you update to the latest version of Roon yet? We had a bug that occurred when using ports over a certain number, and we fixed this in a recent build. Since you only tried ports over 20,000, were you possibly impacted by this?
If you connected it directly to the Netmaster, I wonder if the IP address or port configuration settings in Roon need to be adjusted to reflect the IP configuration of the Netmaster?
