DSL Embedded :: Networking questions

I have the embedded version of DSL installed on a memory stick, and I'm running it on XP through Qemu.

The network itself works, I can browse the web interface of my router & I can ssh to one of the other machines on my network.

However I cannot browse the internet. If I try to add the router as a default route, I get an error that the network is not reachable.

The IP assigned to DSL is 10.0.2.15/255.255.0.0 and the rest of the network is 10.0.0.0/255.0.0.0

It just struck while writing this that it could be the netmask of the DSL instance, does that sound about right?
