lampAs I've talked about before, a problem with #ipv6 is that when your prefix changes, you have to update all your config. My prefix from xfinity changed and I had to manually update all my static DNS, firewall rules, wireguard configs.. The "correct" solution to this seems to be #NPTv6, but #Mikrotik doesn't support it. So it's tempting to just do #NAT 66 and have it work the same as #IPv4.
Like the only advantage of having proper #IPv6 is being able to access the same addresses both inside and outside the network, with just a firewall exception, so no need for split dns.
But it annoys me to have internal configs depend on volatile external factors. NAT makes a nice isolation between public and private network so external changes dont affect internal setups.
