It has previously been recommended not to use both allow /and/ deny
statements in a configuration, only allow /or/ deny statements. But I
don't remember if that was only within one pool declaration, or a common
recommendation.
Are all your boxes located in the same VLAN? If they are, then you might
need to put the 10.5.0.0 and the 10.6.0.0 subnets into a shared-network
statement, otherwise the DHCP-server doesn't know that both subnets
share the link. If the VLANs are different, then I would check the
network a little bit further for wrong IP addresses on the router or
similar.
Other than that I don't see any problems. Would you mind sharing the
class definitions as well?
