[Click] FromDevice(lo) -> ... -> ToHost(lo) issue

I am trying to build a kernel configuration which intercept packets on
the loopback and process certain UDP packets. Other packets should just
be send back to host for other applications to process.
My configuration is:
FromDevice(lo) -> Strip(14) -> CheckIPHeader() -> IPPrint('lo in') ->
loClass :: Classifier(udp dst port 3070, -) -> MyElement;
loClass[1] -> IPPrint('lo out') -> Unstrip(14) -> ToHost(lo);
I am able to observe the packets on loopback, but the other applications
with open sockets doesn't get the packets. If I uninstall my
configuration it works as intended via loopback. Any help would be much
appreciated.
Bests,
Martin D
