[K12OSN] DHCP server problem

[John Simovic <jsimovic tpg com au>]

Hello all. I installed k12ltsp4 and have a server with 2 nics. One is 
for ltsp and the other to connect to the existing network. They are 
bothon different subnets and the one on the linux ltsp side 
(192.168.5.1) has a dhcp service running. The thing is, windows clients 
on the 10.14.141.x side are receiving ip's from the dhcp server on 
192.168.5.1. How do i stop this?
