Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

Hi

I get the error below. Have tried setting up my router and nas using instructions and FAQ but it never connects and the error is the same. Anyone who can point me in a better direction?

Welcome to the Roon community, @Kenneth_Thorsager.

The diagnostics you’ve provided suggest that UPnP is not properly configured on your router.

Please first try the following steps:

• Try to enable UPnP/NATPMP in the web administration interface for the router directly upstream from your Core
• Try to manually open the port in your router’s port forwarding configuration
• Make sure the IP/Port matches the Port listed in Roon → Settings → ARC
• Check for any VPNs or Firewalls that might be interfering
• Check if your modem is in Bridge mode

If you continue to experience difficulties, please tag the support team and include the following information:

1. What is the make and model of your modem and router?
2. Do you have any additional network hardware, like additional routers or managed switches?
3. Who is your internet service provider and what is your geographic region?
4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?

Hi Guys

I use a Sagem Router and access point are netgear RBK850 and RBS851
The sagem router is setup as main router and the others as AP. All setting in netgear is greyed out.

Big change from start of today is a changed sagem from being brigde to now router.

Upnp now works. but synology is failing when i test the connection.
I have attached screen dumps from router and synology who seems to talk just fine to setup the roules.

Get this error now:

{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“212.aaa.bbb.mmm”,“actual_external_ipv6”:“null”,“router_external_ip”:“100.kkk.jjj.lll”},
“status”: “status”: MultipleNatFound
,
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.0.1”,“found_upnp”:true}
}

The latest diagnostics you’ve provided suggest there is a redundant layer of network address translation preventing port forwarding.

This can either be at the local-network level (commonly as a result of two routers), or at the level of your service provider (in the form of carrier-grade NAT). It’s important that your NAS and remotes are on the same subnet. Are you using the Ethernet ports on the Orbi to connect to your core?

There are several ways to resolve this depending on the capabilities of the second router (Orbi)

1. ensure the Orbi uses DHCP, and is allocated IP addresses from the Sagem.
2. setup manual port forwarding in the Sagem that forwards to the Orbi
3. place the Sagem in bridge mode

If your setup involves an ISP-provided gateway (modem/router combination) and your own third-party router:

• In the web administration interface of the ISP-provided gateway (modem/router combination), enable Bridge Mode or equivalent, where the ISP-provided gateway does not have DHCP routing enabled.

• Alternatively, if you have already created a manual port forwarding rule in your 3rd party router, you can add an additional rule to forward the port through the ISP/second router.

If you only have one router in your setup or your modem is already in Bridge mode, please take a look through our list of known router and internet service provider solutions, as other users may have already encountered the same situation: ISPs and Routers: List of Known Solutions and Workarounds

You can reach out directly to your service provider to ask if they support port forwarding; this question will often enough to prompt them to explain whether or not the carrier-grade NAT they’ve implemented can function with ARC.

More specifically, you can pass along the following questions:

• Have you implemented carrier-grade NAT for my account level?
• Have you fully implemented IPv6, or do you have IPv4 addresses available?
• Can I request a static IPv4 address to support port forwarding?
• Are there any ports you have reserved at the ISP level I should be aware of?

If you’re unable to locate an existing solution in our #support:port-forwarding-resources subcategory, please reach out to the Roon support team and include the following information:

1. What is the make and model of your modem and router?
2. Do you have any additional network hardware, like additional routers or managed switches?
3. Who is your internet service provider and what is your geographic region?
4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?
