I need to have on the same subnet a dhcp server to distribut 2048 ip adresses, i setup the open dhcp server the range 192.168.1.1-192.168.7.254 wiht the subnet mask 255.255.248.0 and the other dhcp options.
I was expecting that the server start given ip adress after the 192.168.1.254 as been lease.. but that doesn´t happend, i see the log file and it says that there is no free ip adress.
On the webpage the ip adress are set has free dynamic leases.
Can some one explain me why this happend?
Did you set the subnetmask of listening interface to 255.255.248.0 too ?. This is required too.
Version 1.5 onwards this should work straightaway. Not sure how many listening interfaces you have (I guess only one then 192.168.7.254 (with subnetmask 255.255.255.0 can only reach 254 clients. , Make sure your default gateway is set reach all 2048 targets. Alternatively set the subnetmask of this listening interface to 255.255.248.0.
