HI,
I have had a quick look but can't see an answer.
On a USG300 is it possible to have a DHCP range larger than 256 addresses?
Simon.

    That simple ey? Would of been beneficial if the error on the USG was a bit more informative than 'Computer Says No'.
    Thanks though.
    Simon.

    @CRU_Technologies AFAIK someone is managing a firewall should be aware about the 254 hosts limit of .C Class networks (subnet mask 24bits/255.255.255.0).
    I used 23 Bits mask (255.255.254.0) for allowing more than 300 customer devices into an hotspot network.
