    One problem I have is dhcp leakage. I have multiple vlans setup and the dhcp server on the appliance was responding to requests from a subnet that has a windows dhcp server on it. It should have not been responding, however I noticed the issue when I saw it in the Windows Event viewer, it had a DHCP client notification.
