This was asked before, but not really resolved, so I'll ask again in hope of the new tread getting noticed.
There is a "What's New" document for FWSM Software v3.2 (http://www.cisco.com/en/US/customer/products/hw/modules/ps2706/prod_bulletin0900aecd805c34ca.html) which was apparently written in January, but the software does not appear to be available from the fwsm download page (http://www.cisco.com/cgi-bin/tablebuild.pl/cat6000-fwsm).
Is there some reason this software is not publicly available, or is this an oversight? Can we get access to this software somehow? We have a need for some of the changes in that version (specifically, PAT for RTSP).
