The DHCP servers in some routers are surprisingly versatile, I use a
WRT54G running the Tomato firmware. After messing with the config
file one too many times, I decided to look up the DHCP capabilities of
dnsmasq built into Tomato.
I mostly needed it to give out addresses for standard workstations and
the network boot PXE machines for minimyth. Once I figured out the
magical incantation it was easy. Below are the lines I needed to add
the the dnsmasq config.
dhcp-option = 42,<NTP Server IP>
dhcp-option = 66,"<TFTP IP>"
dhcp-boot = "/PXEClient/pxelinux.0",<TFTP Server Name>,<DHCP Server IP>
option 42 passes NTP Server
option 66 passes TFTP IP
the boot line points the boot file on the TFTP server.
