2 ways. the common way is to integrate them with sysctl - eg place them in the /etc/sysctl.conf
file - it will then be pulled in at start-time.

alternatively, add commands to rc.local

ouch. thats a nasty knee-jerk reaction. ISC DHCPD on Linux is soo much better than
any windows thing.  theres a reason why all appliance solutions use ISC DHCPD and Linux.

(higher performance etc can be with ISC DHCPD on a BSD platform.... but for some, the BSD
learning experience is steep and harsh)
