topo:
vm1         vm2
   |                |
   |                |
---------------
|     lswitch     |
---------------
           |
---------------
|     lrouter     |
---------------

vm1`ip 10.0.0.1,  vm2`ip 10.0.0.2,  lrouter`s default_gw is 10.0.0.2(vm2)

In lrouter, the inport and output of the traffic form vm1 to default_gw 
is same, so lrouter will drop it in "Table 34"

In scenario as follows:
vm2 is firewall, all traffic to outside will be send to vm2.

Is it correct?
