Ziggo ISP-Supplied Modem/Router: Roon arc external ip problem

[Henk_Beijsens]

I keep getting the same respons when configuring roon arc.
UPnP and NAT are set and ok. Port forwarding is set to the correct port.
What else can I do?

{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“xxxx”,“router_external_ip”:null},
“natpmp_autoconfig”: {“server_ip”:“192.168.1.1”,“found_natpmp”:true},
“upnp_autoconfig”: {“server_ip”:“192.168.1.1”,“found_upnp”:true}
}

Henk, sorry to hear about your issues in configuring ARC. We need some informationA few questions to help us with a potential solution:

• Who is your ISP?
• What device(s) has your ISP installed in your home? Examples include modems, routers, gateways, WiFi externders.
• Do you have any other networking equipment installed in your network, for example your own router, WiFi extenders, switches?
• What is your Roon Core using as a computer?

Hi Henk,

I am moving this to the Port Forwarding Support section. In addition, could you fill in the form below, so that the additional information will help support when they engage.

One thing I would ask, is if your internet provider is giving you CGNAT service? You might have to call to find out, and if they are you can ask for a direct public IP instead.

Thanks!

==========================================================================

1. Who is your internet service provider?

2. Please list the make and model of your modem and router?

3. Do you have any additional network hardware, like additional routers or managed switches?

4. Does your network have any VPNs, proxy servers, or enterprise-grade security?

5. What machine are you using as a Roon Core, and how is it connected to the internet?

[Henk_Beijsens]

Hi Robert,

My ISP is Ziggo.

I have a Ziggo modem/router connected to a Netgear Orbi RBR50 router plus two satellites.

Roon Core is using my Mac 27 inch with a 8 core Intel i7 processor.

[Henk_Beijsens]

And no VPN or proxy server or enterprise security

[Robert_F (Rob)]

Henk, thank you, this is helpful. I agree with @Rugby’s question to ask Ziggo if they use CGNAT because your ARC error message is not quite the same as a double-NAT error message.

If CGNAT is used within Ziggo’s network, then one option is to request a static IP address for your public IP address. If CGNAT is not used by Ziggo, can your Ziggo router be configured for port forwarding?

[Henk_Beijsens]

Thanks Robert. I will contact Ziggo and let you know after.

No need for a static IP, but for a public IP. See this thread:

SOLVED: Do I really need a static IP to make Roon Arc work?

This gives me indeed the address I got in the error: 81.164.123.198

Hi @Henk_Beijsens ,

I use Ziggo with a ConnectBox without a problem. Do you have the same box?

[Henk_Beijsens]

Hi Joost. I use my own Orbi router, but now I found out that when I change the wi-fi to the Ziggo box the Roon Arc connects correctly. So, I have to get in touch with Ziggo (for now when I’m out of the house I just change to the Ziggo wi-fi to use Roon Arc.)

Description of Issue

I have the same issue. At home on wi-fi ARC runs perfectly fine. But if I turn off wi-fi and my iPhone uses my 4g connection nothing would play and often getting the “poor connection” message. Which is odd because all other apps that I’m using have 0 problems with my 4g connection. This includes Qobuz, Apple Music, VOX, HBO Max and Amazon Prime. Even streaming full hd doesn’t result in stutters.

I’ve tried ARC as well in my car and at work, but resulting in the same issue. On top of the app you see a progress bar that keeps spinning without end, and then the “poor connection” message will show up, or not at all.

Hi @SandsOfArrakis,

I’ve merged your thread for visibility with another user with the same ISP-supplied modem from Ziggo.

First off, are there any diagnostics displayed in the ARC Settings tab in Roon? It’s likely that you’re encountering a double-layer of NAT that is preventing the port forwarding from automatically configuring. Please post any diagnostics visible (make sure to censor IP addresses for security) and the team will be best equipped to support you.

First, please review our port forwarding Help Center guide.

A couple other questions that will help us determine the source of the block:

1. Do you have a second router in your setup?
2. If you don’t have a second router in your setup, then it’s possible you are bumping up against Ziggo’s dynamic IP address assignment, or an issue with assignment in your router. You can verify that your router is set to IPv4, and not IPv6, just for due diligence.

3. I suggest you reach out to Ziggo’s support team to inquire if Ziggo can provide your account with a static IPv4 address if nothing works.

[Joost_Hoogland]

Hi @Henk_Beijsens,

Did you make any progress with Ziggo on your setup to report back here? Could help others with a similar setup.

[connor]

Hi @Henk_Beijsens,

I wanted to reach out, as it’s been some time since I last checked in on the issue you were experiencing. The team investigated routine diagnostics from your account, and it would appear that ARC has been able to successfully connect in what would appear to be mobile playback conditions (4G/5G). Have you been able to successfully contact your ISP to bypass their carrier-grade NAT on your account?

[Jasper_Kunst (Jasper K.)]

I had the same problem. I was not able to access my Roon Core with Roon arc.

My setup:
ISP: Ziggo > Arris TG2492LG (router) > Unify Dream Machine Router > Unify Switch > Roon Rock

Solution: I had a chat with Ziggo to put the router in Bridge Modem, which results in:

-Disabled firewall
-no WiFi
-no NAT
-no DHCP

Next to this I added port forwarding on the Unify router, using the IP from the Roon Rock with port 55000.

Now it works. So happy I can work on my playlist and other music management with Arc while on the train

[SandsOfArrakis (The Spice Must Flow)]

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.

Port forwarding rule set so my ASUS router which is connected through Ethernet gets data forwarded to it.

Forwarding rule set in my ASUS router.

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.

@Henk_Beijsens

. I use my own Orbi router, but now I found out that when I change the wi-fi to the Ziggo box the Roon Arc connects correctly

This is because you remove a double NAT when using the Wifi direct to Ziggo router.

Core → |Orbi / NAT1| → |Ziggo router / NAT2| → Internetwebtubes

Core → |Wifi| → |Ziggo router / NAT1| → Internetwebtubes

If you’re going to use 2 routers you need to port forwarding on both.

1. Ziggo ARC port → Orbi
2. Orbi ARC port → Core

[Frits_Van_Der_Veer]

I also had a arc problem with ziggo/Linksys mesh at home
Turned out: Ziggo had, during an update, un-bridged the ziggo modem hence no arc for.

Since ziggo modem is back in bridging mode all things are fine.
My Linksys mesh is handling all ip numbers etc.

Hi @Henk_Beijsens and @Jasper_Kunst,

Happy New Year and I hope this response finds you well. Are you still having difficulty with ARC?
