I'd've expected that to work.

What does your routing table look like?  You can view it with "netstat -
nr".  I believe when a Linux network interface is ifconfig'd, the kernel 
will add a route for that interface based on the netmask in the ifconfig, 
but you could conceivably have another route that is broader overriding 
the specific route.
