Australia: NBN Satellite Internet (Skymesh/ViaSat) Has Carrier-Grade NAT (Workarounds Required)

Support ARC: Port Forwarding Help
12

Hi @Peter_Treyde,

Thank you for your patience and for the detail you’ve provided so far.

Unfortunately, NBN’s satellite partner (VIASat) has implemented blanket carrier-grade network address translation for their accounts, placing you in the unfortunate group of Roon ARC users who will have to temporarily pursue one of the following workarounds:

  1. request a dedicated routable IPv4 address from your service providers. NBN’s offerings vary considerably from subnetwork provider to subnetwork provider. It’s worth inquiring directly with ViaSat or NBN’s support department whether they offer workarounds for port forwarding, as this is likely a common inquiry.

  2. Consider an unofficial workaround like TailScale, NordVPN, or another VPN, in our #tinkering and #roon sections. Here’s an example thread: Tailscale implementation with ARC to circumnavigate ISP CGNAT

There are other satellite internet providers with similar implementation, most notably Starlink: Note for Starlink Customers. The Roon team is actively working on solutions to allow port forwarding to autoconfigure for more users. Let me know if we can answer any questions in the meantime.
