UPnP ARC issue on router (ASUS AC68U)

“Roon ARC will not be able to access your Roon core” it says.
I have UPNP enabled in my router. Thanks!

Hi @Penny ,

What router model/manufacturer do you have? Can you please look over our Knowledge Base article and see if this helps in your case? Thanks!

I have ASUS AC68U router.
I have UPNP already enabled and i manually forwarded the port.
It cannot connect to Roon ARC.
Should I copy the diagnostic data from the Roon ARC tab in Roon Core here?

Edit. And I deleted the ext IP:

“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:"XXX,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}

Yeah you can go ahead and copy that here.

Hi there!
Roon ARC works perfectly on my setup: Windows 11 Roon Core and FritzBox 7590 router.
Please be aware that in many routers you need to:
1 - turn on UPnP
2 - give permission to use UPnP to automatically configure ports to your Roon core.

Without step 2 RoonARC will not work.

Hi Penny. I accidentally replied with a whisper. Did you see my reply with the screenshots? I am going to provide them here too just in case. This will also allow other users to see the screens.

Fellow ASUS user here. I’m a fan of their very detailed and sometimes confusing config.

Can you check the configuration in the screenshots I supplied? I don’t know if it was one setting or some combination of the 3 but trying to get ARC working on my ASUS I ended up enabling all of these things. Please note that for the second screen shot, the internal IP is not necessary. Screenshots below:

In the WAN section, Internet connection tab:

Under WAN section, Virtual Server / Port Forwarding tab:

Under Open Nat section:

Same here no static IP from ISP as use 5G connection as much quicker than all other network options in my area…

Cannot see why this cannot work, if I can use remote access to PC’s on my network from anywhere in the world, why cannot Roon ARC work in the same way ?


Thanks, but I already put those settings and it doesnt work.
I dont have a “game” and “open nat” option on the left side in my Asus AC68U.

Hi @Penny,

Thank you for confirming.

There is a possibility that your IPV6 is enabled and causing some issues. Can you try disabling IPV6 on your ASUS and try again?

Under Settings>Roon Arc, is the port manually configured to 55000? Go ahead and set it if not. It’s possible that it’s blocked by your ISP. You can verify this by going to https://canyouseeme.org/ and providing 55000 in the Port to check field.

Would you mind sharing your ISP and your modem make/model so we can check some other possibilities?

I found a video that is specific to your model router. Worth a shot anyway. Our routers and screens are substantially different.
