Your route for the 10.0.0.0/24 network would be installed as a /8 in the client. I just checked and I don't even see this option in ISC DHCP3... If this is the case, a workaround would be to set the default gateway on the clients to the Linux router, and let the router reroute the packets to the DSL. Not 100% optimal since the packets go over the same network twice, but you're talking about a DSL line, I don't think it's going to severely impact performance on a 100M LAN. Another option may be to add another NIC to the router and have the router be the real gateway for the DSL. But this may not be an option depending on the rest of your setup.
