I am trying to simplify setup for the new user as much as possible. The 
way I have it, it provides security against intruders for home users or 
users of small networks, without them needing to do a lot of setup or 
have a deep understanding of their network architecture.

I could allow input of subnet size, but that would need to be input for 
each subnet that you have. This seems complicated. Also your IP 
addresses can change. The IPV6 global addresses can be changed by your 
ISP and that may invalidate what you have set up for a subnet you no 
longer have.

If you need wider access you can turn off the ip address filtering and 
then use another mechanism or firewall to restrict traffic.
