I think PIX OS 4.4 does not support access-lists right?
access-list example:
NOTE: Be sure that the deny statements are in the first lines of the access-list and the permits after.
PIX(config)# access-list acl-outside deny ip X.X.78.0.0 255.255.0.0 any
PIX(config)# access-list acl-outside deny ip X.X.79.0.0 255.255.0.0 any
PIX(config)# access-list acl-outside deny ip X.X.80.0.0 255.255.252.0 any
PIX(config)# access-list acl-outside permit ...(Rest of the permit access-lists otherwise all traffic is blocked)
PIX(config)# access-group acs-outside in interface outside
Conduit example:

conduit deny ip any X.X.78.0.0 255.255.0.0
conduit deny ip any X.X.79.0.0 255.255.0.0
conduit deny ip any X.X.80.0.0 255.255.252.0
conduit permit tcp .....
I think it would be good to upgarde your PIX !
There are a lot of nice features !
sincerely
