Dynamic Host Configuration Protocol (DHCP) Server

DHCP is used to lease out individual IP addresses to anyone who configures their system to request one. Other vital information such as subnet mask, default gateway, and name server are also given to the client at this time. The WFG uses a beta DHCPv3 open-source server from the Internet Software Consortium with the additional ability to dynamically remove hosts from the firewall access list when DHCP releases a lease for any reason (client request, time-out, lease expiration, and so on). Configuration files for the server are located in /etc and follow the ISC standard (RFC) format. However, the server executable is customized and does not follow these standards. If the server needed to be upgraded, then the source code would need to be re-customized as well.

The DHCP server is configured to only listen on the subnet interface of the wireless network. This prevents anyone from the wired network to obtain a wireless IP address from this server. As an added security measure, packet filters prevent any DHCP requests coming in on any other interfaces.
