    Firewalla

    The address space of xxx is fairly large, so there is no need to turn it off. Here is my math

    • There are around 3.7 billion IPv4 addresses 
    • the xxxxx part in firewalla is a mix of lower case characters and numbers (9 digits minimum); this means there are (10+26)^9 which is a huge number that's 27000 times bigger than all the available IPv4 addresses.
