Attention Salt. Users in Switzerland: CG-NAT Blocks Port Forwarding, Workarounds Required (See Staff Post)

Hi everyone,

Unfortunately, as @Tobias_Imbach and several other users have already realized, Salt. Mobile SA has widely implemented IPv6 addresses for their residential accounts and uses CG-NAT for that tier. It does not appear that they have a DS-Lite IPv4 tunneling option or PCP support that will allow for Salt. users to either automatically or manually configure port forwarding. So, ARC is limited to home network use and playback of offline downloaded content at this time. Note that the team is actively researching workarounds to IPv4 port forwarding that will potentially allow for our users dead-ended with CG-NAT to access ARC on-the-go as designed. However, we don’t have a timeline or a guarantee of success for these potential future Roon-supported workarounds.

To summarize, there are three current workarounds Salt. users can take to access ARC, although they do fall within the realm of our #tinkering solutions:

1). Contact Salt. support to request a static IPv4 WAN IP address for a monthly fee. Note that, depending on the age of your Salt account, you may be able to grandfather into a static IPv4 if you originally had one reserved.

  1. You can try out TailScale, a workaround explored in our #roon and #tinkering section (see above)

  2. You can try out various third-party VPNs, as discussed here, for example.

Thank you for your patience, and we’ll post here if we find any additional helpful information.
