We have had two incidents with firewall rules recently. First, we had an access rule that was not working. On a whim, we moved it to the top of the list. It began working. We moved it back down to the bottom of the list. It continued to work.
Today, a rule that had been working stopped working the way intended. There is a rule that allows my workstation to talk to a server on ports 2001 and 2002. Today, the FWSM would allow communication via port 2001 but denied communication via port 2002.
Has anyone else experienced similar behavior on their FWSM? We are running version 4.0(4). Thanks!
