Hi @zhiyun_chen,
Welcome back. When I look at the error message, I think there are multiple routers in your setup.
Could you please describe your setup, so which modem/routers are involved and how are the connected. Also please provide your ISP and country.
Thanks.
Kind regards,
Maarten
@zhiyun_chen, as @Maarten_Duits points out, you appear to have 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).
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:
- What is the make and model of your modem and router?
- Do you have any additional network hardware, like additional routers or managed switches?
- Who is your internet service provider and what is your geographic region?
- Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?
Hey @zhiyun_chen,
Following up on this thread, were you able to get Arc sorted out? If not, please review both @Maarten_Duits and @Martin_Webster’s helpful replies.
I’ll be on standby for your follow up
