Known Carrier-Grade NAT Issues Requiring Workaround or #tinkering

This is a list of internet service providers known to have innavigable carrier-grade NAT implementation at this time. If you are having difficulty with port forwarding and your ISP is listed below, please first review our Help Center guide to verify there isn’t a resolvable issue in your local network setup; these CG-NAT blockages do not necessarily apply to every user. Note that Roon CG-NAT is a known snag with the initial design of ARC that will unfortunately force some customers to pursue workarounds, but the team is actively researching methods to hopefully more widely democratize access to on-the-go playback for Roon 2.0 users at some point in the future.

Please see the staff post in each case below for additional context.
