@puppygirlhornypost2 Every IPv6 debate ever. Ugh. Even if you tell them that NAT doesn't prevent access to your network at all and that it's a work of firewall, which does it with or without NAT, they don't care. The most bizzare exchange I had continued "Yes, but firewall is always a part of router with NAT" as if that was some kind of proof that you need NAT.
