isc-dhcp-server issue, not broadcasting on eth0:1


Hello,

On a server that provides dhcp services to a few client pc's I have 3 subnets: 192.168.0.0/24, 192.168.1.0/24 and 192.168.2.0/24.
the server has 2 virtual interfaces and one hardware interface for these subnets.
I want to seperate hosts on the network and use the 192.168.0.0/24 and 192.168.1.0/24 only for known devices. I have their mac addresses and they have a static lease in the dhcp config file. For the unknown hosts I have the 192.168.2.0/24 network.

The problem I had is that the unknown hosts only get their IP assigned through dhcp if I configure 192.168.2.1 on the hardware interface. for the other networks it works fine to get a dhcp lease if I configure the 192.168.0.1 ip on the virtual interface.

Why doesn't the server hand out ip addresses to untrusted hosts (should get a 192.168.2.x ip) while it does for trusted hosts when the IP address of the hardware interface isn't in the same subnet?

I hope I've made the problem clear, it was quite hard to do...

I'd like to understand this.

thnx in advance,

Steven

Will be more clear with your config file.

What config file are you referring to? Networks? dhcp config?
