FreeBSD DHCP server on multiple interfaces

Question

I have FreeBSD server (7.2) which has a lot of interfaces (vlans, count near 100). I want to configure DHCP server with separate pools for each interface. What program should I use? Thanks for any advices or config examples.

Answer 1

by reading http://www.freebsd.org/doc/en/books/handbook/network-dhcp.html#NETWORK-DHCP-SERVER you can find out, that you:

• can use isc-dhcp31-server
• can configure pools for each subnet you want

subnet 192.168.24.0 netmask 255.255.255.0 { ... }
subnet 192.168.23.0 netmask 255.255.255.0 { ... }

• you can make isc-dhcp listen on the devices you want (/etc/rc.conf):

dhcpd_ifaces="dc0"
dhcpd_ifaces="vr0"

another option is to use dnsmasq, comes with a dns-cacher included.
