Well I finally have my setup working with ARC. And I didn’t have to get Ziggo to put the Ziggo Mediabox into bridge mode. So it still has its DHCP, NAT, WIFI and firewall enabled. The only thing I disabled on both the Ziggo box and my ASUS router is UPnP.
With these settings Roon ARC works like a charm here. Rock solid connection to my Roon Core which is running on a 2017 MacBook Air connected through 5g wifi.
Could you post a screenshot of your port forwarding rule and a screenshot of the port Roon is looking for Roon Arc. This can be found in the Roon App under Settings → Roon Arc.
After disabling UPnP and setting it back on I now have a second problem that I can’t see my streaming devices anymore both in Roon and other music software.
Could you change the protocol to TCP/UDP (or sometimes it says “Both”) in your port forwarding rule. I know Arc only needs TCP, in my case i needed to set it on “Both” (my isp is KPN).
Could you go to https://portchecker.co. Your public IP will be shown there (so don’t post a screenshot of it anywhere). In the port number field enter 55002 and hit the “check” button.
If everything is configured correctly the message should be that the port is open.
What it shows, is that from the outside world your machine (over port 55002) isn’t visible. That’s also the reason why Roon Arc isn’t working. Could you try the following: in the Roon App under settings → Roon Arc change the port number to ie. 44135. Change your port forwarding rule to this number. Then try Roon Arc and the port checker for this new port number. Some ISP’s block some range of port numbers. Don’t know if this is the case with Ziggo. It’s worth a try.
Maybe you already did it, but after changing the port forwarding rule, did you reboot your router and core?
Hi
My 2 cents ( had also issue with RoonArc). Ignore if not relevant.
Make sure your upc router is in bridge mode ( if required for you home-WiFi)
I have Linksys mesh in-house dealing with all the IP-adresses. Upc router in bridge mode. RoonArc works.
Switches
Two Netgear switches (GS108T), both directly connect to the Ziggo modem
→ first one sits on the second floor
→ second one sits in the attic provides fixed internet for my LAN
My working, listening and DJ room in the attic
Local Area Network and devices
My old W7 Windows PC
My new W11 Windows PC (Dell XPS 8950, 12th gen i7-12700k 3.60GHz, 16GB Ram, W11 Home 22H2)
My Mac- (Traktor DJ Software, +Mixing gear) and Windows laptop
My old NAS (ReadyNAS) and new NAS (Synology)
Two NAIM streamers (UnityQute and NAC N-272) → I use upnpbridge software to make them proper endpoints)
Roon Core is installed on the W11 computer with a collection of approx 350k tracks.
I also use MediaMonkey 4, which is installed on both my old and new desktop computers.
Wifi
Lowband Wifi on the Ziggo modem is on as the old Logitech Squeezebox doesn’t work with the modern Deco’s (hence not in bridge mode). This is for internet radio and streaming my collection via roon in the Kitchen (sits in the basement).
3 TP-link Deco SmartWifi pods
→ 1 directly connected to the modem in the basement
→ 1 on the ground floor
→ 1 on the first floor
Provides enough fast Wifi coverage for the whole house.
Are these switches managed or unmanged switches? If it are managed switches, maybe there is something wrong. Is the W11 machine connected via Wifi of direct via cable to the ziggo router? If WiFi, is it connected via the TP-Link smartwifi pods?
