DHCP Assigning IPs Outside of Allowed Range

I have a ClearOS server running V7 with latest updates. I have two VLANs that split an "open" (but still password protected) wireless network from the main wired and "secure" wireless network.

The problem I'm having is that ClearOS seems to be ignoring my DHCP range for the secure network. I have it giving out IPs in the range 100-229 but I have several clients getting IPs in the 230+range. I've checked all of the configuration several times and nothing seems out of place. The clients are iPads, desktops, laptops, and android phones. Some are wired and some are wireless.

This is a pretty big issue because I've given the 230+ range to another guy for testing networked equipment and he uses static IPs. It's only a matter of time until there's a conflict that shuts down his testing.

This seems to be a recent thing within the last month.

Any ideas what's going on?

Thanks,

Rob
