I haven't implemented the function, so I cannot comment more about its
internals, but you can chain it with the match of subnet for private
ipv6 using:


Of course, you can add a new function, if you want. An alternative
coming in my mind is to add the subnets in address table grouped with an
id that you use with allow_source_address().
