Re: Cisco recommends us to replace conduits with access-lists b
Well, I am not a guy from Cisco. However, I know what you are talking about. During my PIX firewall class the instructor indicated that Cisco is trying to make the PIX software more IOS like. So, access list will be the preferred method in the future. So, after I got back from training I removed all my conduit statements and changed them to access list. I had to speak to one of the Cisco Engineers when I had a problem, but they said it was my choice whether to use conduits or access list.
As you learned when you apply an access list it defeats the ASA feature in the PIX. You now have to specify all outbound traffic as well.
It may be more of a hassle initially, but access list do provide tighter security.
