The problem is that the router sends the "helped dhcp packet" to the dhcp server with a source "giaadr" of the routers primary address. The dhcp server receives the packet, sees the source is in 192.168.2.0 range and tries to pass out an address in that range from it's database. I'm betting that it doesn't have a scope for the 192.169.2.0 range, so it fails. I'd swap the primary and secondary addresses on all the routers if you can and it will work.
