Packet RESET don't pass through ASA

Hi everybody,

I'm having a weird behavior in a connection. My connection is TCP originating from inside to outside. A few times from outside there are Reset packet coming (for this connection originated from inside) that don´t pass through the ASA generating disconnection. This behavior is not for the whole Reset Packet because a few are coming through.

I can't detect why the ASA drop this packets. I'm trying to make a correlation between the packet that dont pass the firewalls and the ASP table from the ASA (sh asp drop). But I can detect why the ASA do this.

Somebody know how can I detect the cause of this?

Best regards.

Javier
