I haven't looked into IPv6 before since my old router couldn't handle it, but now when switching to a RT-AC66U with Asuswrt-Merlin I realised that maybe I can turn on IPv6.
But I am wondering how the router will handle IPv6 if I just "turn it on". (I'm not yet sure what type of IPv6 access I can get, I don't think native works but 6to4 or rd might work.)
First of all, will all my LAN devices capable of IPv6 suddenly become externally accessible? Or will there be default ip6table rules working as a firewall, so I will have to do port forwarding for any servers on the LAN?
When everything is behind NAT that gives an extra level of security, but if that level is removed when using IPv6 the requirements for keeping things shut will increase...
Will I have to set up IPv6 addresses separately in dnsmasq? (I have some static DHCP leases set up, I guess those won't work for IPv6 since they are based on MAC and IPv6 DHCP doesn't seem to support MAC? But will dynamic DHCP addresses work?)
