Hi,

you can tweak the NAT timeouts to lower values and/ or limit the number of entries in the NAT table.

Hi,

I think you should police the P2P traffic but anyway your timers musn't be too aggressive and I think that trial and error is the way you must go.

hi,

the error logs could be a bug. try to upgrade your IOS and see if it resolves your issue.
