As such a customer, I’m worried that my ISP would eventually bait-and-switch me from routable IPv4 + optional IPv6 to CGNAT IPv4 + IPv6 when convenient to them. Sorry, but I’m not risking going behind a 1:n NAT layer that I don’t manage.
- detaro 6y agoOf course nothing stops an ISP putting you behind CGNAT IPv4 without IPv6.
- rescbr 6y agoSure, but the threat of me cancelling and switching to another ISP as the service is now unsuitable for my needs is enough to keep them from doing that. Does this strategy work? Maybe, when I upgraded my plan they wanted to switch modems, the new one didn’t have working bridge support, and I said to them it was a requirement for me. No bridging, revert everything. The field tech escalated to engineering and they approved a business-class modem. I expect the same with IPv4, even if I have to pay extra.
- jiggawatts 6y agoKeep in mind that many Australian Telcos are already using CGNAT, although they do allow customers to opt out. I've had to opt out, because CloudFlare was showing me Captchas all the time. For example Aussie Broadband had a nice writup of their CGNAT setup: https://www.aussiebroadband.com.au/wp-content/uploads/2019/09/Ausnog-2019.pdf https://www.aussiebroadband.com.au/wp-content/uploads/2019/0...
