ARC with Asustek GT-AX11000 router not working

I have tried rebooting everything. Upnp is enabled, I have manually enabled a port. If you have this router and get ARC working, I’d appreciate any tips. Thanks.

Hey @John_Powell,

Thanks for taking the time to write in, and my apologies for the delay in follow up. After taking a look at the error code you’ve provided, there might be a few things at play.

  • Multiple NAT situations with multiple routers that need to be port forwarded
    Are your switches all unmanaged? Can you confirm that your modem has been set to bridge mode, with your router having the proper port forwarding rules set (and properly matching port numbers from Roon and your router)?

You can read more info on the subject here :

If you can’t figure out how to put it into bridge mode let us know the modem model/manufacturer. You may need to give your ISP a call to request or confirm you are running a static IP.

I will be monitoring this thread for your reply :+1:

I finally got my ISP to assign a static ip. The problem is resolved.
