IPv6 setup with NAT
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have an Archer c8 and wanted to setup ipv6 on my local network due to an issue with a tablet not connecting to internet without ipv6. When I select ipv6 I get dynamic slaac/dhcpv6 for WAN and all of my LAN options (dhcpv6, slaac/stateless dhcp, slaac rdnss) all give my devices 2001:56b:fa03:d200::/64 prefix which seems to expose all my devices addresss to the internet. for what I've read I should be getting fe80 prefix and 2001 is for global, correct?

Hello,
As far as I know, the IPv6 address with the fe80 prefix can only communicate in the local network, and it won't communicate over the LAN, which means if you get the fe80 prefix address for the IPv6 connection, you won't be able to access the internet.
The address with the 2001 prefix is the one that communicates over the internet, but don't worry as there is an IPv6 firewall on the router which blocks the external access to the LAN device automatically to protect your internal network and ensure its security, and that firewall currently cannot be disabled.
Hopefully, that answers your question but let us know if you need more details.

So IPv6 has deprecated NAT, got it, thank you.
