I installed it on a 515 and it's been working great. I also installed the beta pdm that was released and it's working as well. That's too bad that baddos had a problem with it, have you heard back from Cisco yet? With the new version one of the new features is that you can run the PIX as a DHCP server, so I have installed a DCHP server on the DMZ interface and hung my WAP device off of it. Then utilizing the Cisco VPN client I can get into my network or out to the net, without the VPN client you can't get anywhere.
