The problem is you need to also export that route.
you can add the 10.0.1.0 network to the route so it can access this network but you also need to recipricate that on the other network...

you could add
route add 10.0.1.0 netmask 255.255.255.0 eth1 on the server
and on each client you could add

route add default gw 10.0.1.0
however you then need the wireless application box to route across the two. With a hardware box it does this for you using NAT,

I think IP tables is on the liveCD so you could try a script to add my stuff into IP tables.... a look through man IPTABLES should give you the syntax.
(unless you setup DHCP and BIND though you will have to set up each client by hand.....)

BTW this is actually working right now... and I guess its what you actually wanna do!!!
