Hi there! I have installed an EFW 2.5.1 and in the services tag / DHCP /+ Settings y checked the option "Allow only fixed leases". If you connect your laptop or pc to the network dont work, only if I enter your MAC address manually. Ok, but still if you set your IP manually you will be able to browse internet and network anyway. ¿How can I do for allow only hosts listed in my MAC address table?

Thanks a lot for reply.

Try disabling fixed lease option.

Sorry, I think was confused by your question.

A fixed lease in DHCP allows a computer / device to always recieve the same IP Address. The DHCP server reads the MAC address of the NIC and then assigns it the IP address. You will have to enter the MAC address correctly for it to work.

Thanks for reply. I have a list with users, mac address and IPs, there is no problem.
If you connect your laptop in my network, you dont receive an IP because the only fixed leases is checked, but if you set and IP by yourself you will be able to connect to the network and browse the web. So my question is...
¿how can I enable computers only from their mac address?
