DHCP for multiple networks

Iam setting up a router. This particular box will manage connections from as many as THREE seperate networks (3 seperate NICs) onto one internet connection. The standard DHCP server (dhcpd and udhcpd) are only rigged to provide IP's for one network at a time, when I need at least 2, if not all 3 to have dhcp. The scheme is as follows:
eth1: offce 192.168.3.0/24 (a 8-computer fixen-node wired office LAN)
eth2: floor 192.168.4.0/24 (variable-client wireless setup)
eth3: wired 192.168.2.0/24 (variable-client wired setup)

I need dhcp services for all these... any suggestions on how to do about this?

I was always under the assumption that you had to configure each interface.

Gentoo-Wiki has info on this: http://gentoo-wiki.com/HOWTO_setup_DHCP

that wasn't very helpful, unfortunatly.
Now I'm thinking that i'll need to run different dhcp servers for each interface.

no

all you need to to is to have 3 different subnet statements inside your dhcpd.conf.
Additionally you can define >1 ranges per subnet statement - e.g. if you want to have in 192.168.4.x dhcp address from*.10-20 and *.80-253.

Each subnnet statement should have its own options set, especially gateway, broadcast address etc.
