Make sure that ip forwarding is turned on in your kernal; use adb to check
the variable ``ipforwarding''.  Also make sure that you've got the proper
default routing set up on both your hosts on either side of the host doing
the routing so that they know how to get to each other.  I've noted
problems doing this until I used the ``default'' option to route instead
of trying to specify the network explicitly.
