MSS clamping of 1432, or interface MTU of 1508 with PPPoE MTU of 1500 (note that the config tree in Edgerouter tries to set an MTU of 1412 if it's blank and you make changes to something unrelated)
Since I enabled IPv6 in my house, Netflix has basically not worked - the website doesn't even load. I contacted Netflix support who told me "IPv6 doesn't work with IPv4 tunneling". Now, I'm not expert, but I'm pretty sure I am not tunneling. My ISP provides a /56 prefix, and my router and devices use SLACC to get a public facing IP. Tracert to netflix.com shows a straight IPv6 connection the whole way.
If I disable IPv4 on my PC, I still have connection to IPv6 enabled sites, but Netflix completely refuses to load unless I disable IPv6. Netflix themselves told me I should "disable IPv6" if I want to use Netflix.
I personally would rather not use it, but I have family members in the house who watch Netflix a lot, and it's getting frustrating when casting to Chromecast takes 3+ attempts before it kicks in.
Has anyone else experienced problems?
Edit: Thanks for everyone willing to offer help with my problem. I will be trying connecting with the stock ISP router when I can, but unfortunately living in a house with other people, I can't just start booting everyone offline.
Netflix does occasionally work with Chromecast, just takes a few goes, which is a pain, but I will look into what I can do. I don't think there's any way of limiting certain devices to NATed IPv4, so looks like I'll have to live with the problem for now. Maybe start shoving a WiFi point through an IPv4 only VPN and see if it fixes things

My isp give me /56 subnet so no VPN is in play here.
