Yup, absolutely. I'm so annoyed by this. I haven't been able to get either my Comcast IPv6 address pool set up and usable throughout my home network (three switches and two Unifi Pro 6 WAPs, across a few VLANs), nor my HE.net tunnel.
I use Ubnt for layer 1 and 2. Their switches are nice if your needs can be met by their spog. Same with their access points although I haven’t see a good one from then since WiFi 5. Their latest WiFi 7 ap is top dollar but used last generation chip and has a cooling fan :[
So annoyed.
