I have an interestesing and very anoying situation. A FWSM is blocking traffic to a specific host for an unknown reason. This was working until a few days ago.
I have checked, and the traffic is hitting the interface according to a capture command. However there are no hits on the access-lists being recorded. There are no shuns and the xlate and local-host connection tables look fine.
I can connect to other devices on the subnet from the same source address with no issues.
We have tried reloading the FWSM, but that hasn't helped. any other ideas appreciated.
