[Click] problem with StaticIPLookup

[Victor]

I am really confused with how "StaticIPLookup" is used for packet forwarding
in basic-router

 In my basic-router I (see below )  I have configuration for the forwarding
between 192.168.1.x and 192.168.10.x where (as far as  can see )
StaticIPLookup output 1 of 192.168.1.x is sent back to eth0, StaticIPLookup
output2 of 192.168.10.x is sent back to eth1, and both are sent to the local
stack (ToHost).

Can someone be so kind to explain the forwarding logic? I would expect to
see something like:

"take output of 192.168.1.x, if destination address belongs to 192.168.10.x
- send it to eth1".  

Or, is my basic-router.click not created correctly?

Thanks
