   Yes, that is the kind of thing but.. there was a bug in the pfSense    
   firewall rules. pfSense is a freeBSD firewall/router.   
      
   The bug was that pfSense allows you to predicate firewall rules on an    
   "alias", which can be a list of Full Qualified Domain Names. Something    
   like if the source host FQDN is in this alias, route over this gateway    
   to the WAN. The FQDNs resolve to an IPv4 and IPv6 addresses and then    
   checks the IP value in a packet and routes accordingly. This works fine    
   for a WAN FQDN, like e.g. www.google.com, it includes both IPv4 and IPv6    
   addresses. However, for hosts on my LAN, e.g. myhost.home.arpa if there    
   was an IPv4 address it gave only IPv4 and ignored the IPv6 one. I can    
   work around it by creating an extra FQDN for IPv6 e.g.    
   myhost.ipv6.home.arpa, but it takes time to understand why things don't    
   work.   
      
   Then there is the issue of the extra random IPv6 addresses it was    
   creating, which aren't included in DNS, in the FQDN at all.   
      
   That is the second IPv6 bug in pfSense, after the MTU/packet    
   fragmentation bug I mentioned earlier, which I'm still trying to get to    
   the bottom of.   
      
   IPv6 seems surprisingly hard. Surprising if a significant proportion of    
   people are using it.
