Not trickery. Assuming that there's a router in your environment, you need to put a helper address on the router for each subnet for which the DHCP server will be serving addresses. (You can run multiple subnets without a router, but it's really a bad idea.)
For instance, on my HP 3400cl core switch, two of my vlans are set up as follows: vlan 111 name "VLAN111" ip address 192.168.xx.xx 255.255.255.0 ip helper-address 192.168.xx.xx tagged 25-47 exit vlan 112 name "VLAN112" ip address 192.168.xx.xx 255.255.255.0 ip helper-address 192.168.xx.xx tagged 25-47 exit It'll be very similar syntax on a Cisco switch for the helper address. The router then forwards the broadcast packet with to the DHCP server. Kurt On Fri, Aug 12, 2011 at 08:44, Matthew W.
