@cary1102 For that to work you need to push the router/gateway information to the clients in the 10.10.222.0 subnet. Add the following line so your config looks like this:
subnet 10.10.222.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option routers 10.10.222.XXX;
...
Put in the gateway IP address instead of XXX. I suppose you have a router/gateway that is making communication between the two different subnets possible?!?
You need to know that there might be other obstacles still in front of you. The clients use a couple different protocols like HTTP (easy), FTP and NFS to communicate with your FOG server and so the gateway needs to forward all those for the clients to be able to work properly.
