hey guys i have a question my hotspot works fine in ether4 at the 10.12.0.0/24 now my pool range is 10.12.0.20-10.12.0.254, my problem is dhcp lease is almost full how do i expand my dhcp? ori will add >> next pool range? like 10.12.1.20-10.12.0.254 << is this correct? 
please help me
You’ve basically assigned the entire /24, if you assign IPs outside of that range and a gateway within it the clients won’t be able to get to it. The cleanest solution is to grow the network by changing the netmask and then adjusting the pool.
ok, thanks fewi for advice the solution
