I am trying to enhance my shorewall(6) firewall without breaking it, and prepare an upgraded one for future use. Out of interest, a relative has a brand new BT domestic FTTC connection which came with a dynamic IPv4 address and an IPv6 address with TTL 10 years, but the Hub6 tells me that it does not have IPv6 DNS.
