Based on the logs you provided earlier it would be on the Cisco side, 
not your Openswan side.

We know:
The tunnel is up.
Packets are not making it through for some reason.
Since there is no filtering going on with your Linux box, there must be 
filtering going on in the Cisco router.

Option 2 is that it could be some funky routing problem.
