Is there a piece of hardware failing between the IPCOP Green Interface and the hosts your trying?
Try to connect as directly as you can to the green interface to isolate possible hardware failures in switches /routers that may not be passing the DHCP request on to the IPCOP. ALso makes sure your IPCOP harddrive is not at capacity.

Maybe I am not being clear. The DHCP server is not dishing out ANY addresses to ANY device that is contacting it. I tried a few IPods and a few workstations and when I set them to automatic discover / DHCP - they try for a while and then fail. The PC boxes tell me I have a limited connection and when I check the IP "assigned" to the box it is a 169.X.X.X address which is not really an assigned address - but what a windows box will plug in if the DHCP process fails. Now the weird parts - This was all working fine before late Thursday / Friday AM - From what I can tell the DHCP server IS up and running - When I use the Microsoft Rogue DHCP tool to see if there is more than one DHCP server on the network it sees the one DHCP server (The IPCop box) AND it reports a valid IP that the DHCP server would be handing out - When I down the DHCP server and run the Rogue DHCP server tool I see NO DHCP servers on the network. So - the DHCP is there, it is running, it is handing out IP's to the Rogue DHCP server tool BUT No device / PC etc. is successful in communicating with the DHCP server and assigning an IP that the server is providing. Any ideas would be GREATLY appreciated! -----Original Message----- From: tech-geeks-boun...@tech-geeks.org [mailto:tech-geeks-boun...@tech-geeks.org] On Behalf Of Heath Henderson Sent: Friday, September 24, 2010 6:38 PM To: Tech-Geeks Mailing List Subject: Re: [tech-geeks] IPCop - DHCP not responding. Couldn't you just add a static entry into ipcop to always dish out something out of the dhcp range to that box? -Heath Henderson On Sep 24, 2010, at 4:25 PM, "Charlie Niehaus" <cnieh...@altamont.k12.il.us> wrote: > Bit more info. > Using a Rogue DHCP Checker program (Neat little app at: > http://www.snapfiles.com/downloads/roguedhcp/dlroguedhcp.html) > I see that my DHCP is indeed running, and that it is handing out IP > addresses with numbers in the range I have specified.
