Scott, Here is the error I am seeing when a request is made from a host in VLAN40 10.200.6.0/24:
DHCPDISCOVER from 00:0c:29:54:6f:b1 via 10.200.6.1: unknown network segment If I switch the host to VLAN42 I get a similar error: DHCPDISCOVER from 00:0c:29:54:6f:b1 via 10.200.7.1: unknown network segment It looks like the requests are coming from the correct network.

You have 10.200.6.0/24 and 10.200.7.0/24 > configured, but maybe the request is coming in from 10.200.5.0/24? >
