NAT is neither a privacy nor security feature, what are you talking about? Have you actually tested what your CPE does when it gets packets addressed to internal IPs from the WAN port? Almost every time, the answer is just pass it on to the target host. Thinking NAT is a security feature makes your network MUCH less secure. As for privacy - you can fingerprint individual devices pretty trivially, and with privacy extensions for SLAAC you can only tell what /64 network it's coming from, which is no more information than IPv4 (unless you're behind CGNAT, but frankly being behind a 4-to-4 CGNAT shouldn't count as internet access because you literally can't get incoming connections.) |
