Welcome to the Roon community, @Walu_Ye.

The 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).

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?

More specifically, you can pass along the following questions:

  • Have you implemented carrier-grade NAT for my account level?
    Yes
  • Have you fully implemented IPv6, or do you have IPv4 addresses available?
    only IPV4 being used
  • Can I request a static IPv4 address to support port forwarding?
    192.168.0.1
  • Are there any ports you have reserved at the ISP level I should be aware of?
    no

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?
    modem: Advan A10
    Router: tp-link TL-WR844N
  2. Do you have any additional network hardware, like additional routers or managed switches?
    Router: tp-link TL-WR844N
  3. Who is your internet service provider and what is your geographic region?
    by.u by Telkomsel and Indonesia
  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?
    both modem and router are in bridge mode

The responses to the questions do no make complete sense, and are most likely incorrect.

The IP address 192.168.0.1 is a private IP address in your network; your public IP address is 182.-.-.-. Therefore, it’s unlikely you have a CNAT service.

Moreover, I doubt your modem is in bridge mode—did the ISP tell you this?—and the router certainly is not.

Most likely, your ISP modem (Advan A10) has the 192.168.8.0 subnet, and your router (TP-Link TL-WR844N) uses 192.168.0.0.

Therefore, you need to set the modem up to use bridge mode. Please refer to the manual or reach out to your service provider.

My modem advan a10 does not have bridge mode feature only dmz and my router tp link wr844n
Only in ipv6 had pass through bridge mode.
So do i had to buy another modem thats support bridge mode ?

Tbh i just want to try roon arc so badly…

Having re-read the thread, I note that you have an Advan CPE 4G router, and therefore CGNAT, albeit an IPV4 address.

Therefore, I don’t believe ARC will work with your ISP. However, please wait for a reply from @support.
