No secret - just define the subnets (note: this is NOT a
shared-subnet) and configure helpers in each router.
If it isn't working you need to do some troubleshooting :
1) Look in the server logs, is the server getting any requests
2) Look in the server logs, is it giving out any offers or logging
any reasons not to ?
3) Start sniffing traffic on the wire (I use Wireshark) to see if
there is any DHCP traffic. You need to do this both on a client
network and on the server network for the full picture.
