Hi,

I went through the outputs and the only thing i see which might be related would be the denied connections on the ASA evice.

Rest all the things are fine. I also see that the ASA device is running a very old and unstable code :- 8.21 , so i would recommend an upgrade to the 8.2.5 if possible the latest interim and i think that should take care of this issue.

Thanks and Regards,
