For some reason all the addresses in my pools keep getting eaten up. Here is some of my log:

04:15:12 dhcp,info,debug dhcp1 deassigned 10.5.10.73 from 00:12:F0:99:77:5A
04:15:23 dhcp,info,debug dhcp1 assigned 10.5.10.136 to 00:12:F0:99:77:5A
04:15:23 dhcp,info,debug dhcp1 deassigned 10.5.10.136 from 00:12:F0:99:77:5A
04:15:34 dhcp,info,debug dhcp1 assigned 10.5.10.72 to 00:12:F0:99:77:5A
04:15:35 dhcp,info,debug dhcp1 deassigned 10.5.10.72 from 00:12:F0:99:77:5A
04:15:45 dhcp,info,debug dhcp1 assigned 10.5.10.199 to 00:13:20:02:1D:20
04:15:45 dhcp,info,debug dhcp1 assigned 10.5.10.135 to 00:12:F0:99:77:5A

It goes on like that for about 20 or so more addresses. It is not always the same MAC address either. I think I have seen about 90% of the computer on my network that use DCHP do this. Any one know why and or how to fix it?

Here is my config if that helps:

maybe create for boogy man static ip adress, so he cannot change ip anymore.

or block that address stealer

Most modern DHCP Servers has a option 'one lease per host'. MT should perhaps look at adding such a option

It is not just happening with the client in my example above. It has done the deassign assign thing for almost every one of the clients connect. In some cases it just deassigns and re-assigns the same IP so the clients DHCP client thinks that the address they recived is being used by someone else.

You could just add a static lease so that mac address only gets one, and the same, address.

Why do you have so many addresses in your pool, instead of just a range?

Uhm, from my view there is something fundamentaly wrong with your config.... how can you create 4 different subnets on the same LAN through the same adapter, assign each of them (by defining adresses instead of range) dynamic address from the machine having the 4 addresses and expect things to work???

If you want to divide/shape/sort traffic from diffent users on the same LAN you need to do some more thinking

I have never seen a config where someone hasn't used ONE dhcp pool for EACH physcal network, having several DHCP pools for the same physical network (unless you manually handle the assignements through dedicated MAC/IP pairs) is asking for trouble


/Jörgen

Good point!

One pool on one Interface, otherwise DHCP (and the client for that matter) won't know which IP to request and/or assign...
