I have an ASA 5510 8.4(5) in one of my remote offices. it's got a tunnel back to my main site.
the past 2 nights it crashed around 3:00 am and you couldn't do anything but power it off and back on again.
I noticed it was externally pingable, so I turned that off today.
One thing I am noticing in the ASDM logs that some addresses are trying to ping the inside interface.
I don't know the addresses though. they are not one of any of my subnets.
any idea how I can track that down?
