is there a way i can setup dhcp to give ip to users with subnet
255.255.255.255 ???

i want to set this for my wifi network,
so that all users cannot connect to other users.
all they allow is to access to the internet gateway.

i have gprs connection to operator that gives me private ip with this subnet and
my ip is also the gateway. so it only allow us connect to the internet.


how can i implement this?


It's not clear exactly what you want to do, but my guess is that you want clients to be given a netmask of 255.255.255.255, so that all traffic goes via the default route.

In that case, adding

dhcp-option=1,255.255.255.255

should work. 1 is the DHCP option number for the netmask DHCP option, and setting this explicitly will override that default value which dnsmasq sends otherwise.
