If you look back at Figure the NIC labeled 3 would be your firewall. It should have ports 67 and 68 closed. If ports 67 and 68 are open someone outside your network would be able to issue DHCP requests and receive leases. The leases provide valuable information on your network such as IP addresses and subnet masks routers DNS servers and more. This is known as footprinting. Options You can add options to any DHCP lease. These provide the DHCP client with additional TCP IP configuration settings. Common DHCP options and their option numbers are as follows 003 Router also referred to as default gateway 006 DNS Servers 015 DNS Domain Name 032 Router Solicitation Address 044 WINS NBNS Servers 046 WINS NBT Node Type 060 PXE Client You can add options at the server level or at the scope level. Options added to the server level will apply to all clients unless the option is also assigned at the scope level.

If WDS and DHCP are both installed on the same server you have to modify the default settings. Since a client machine must have an IP address before it can .
