Re: The access-list permit ORIGIN to ANY (internet) problem X DM
The only way you could do this is what I think you have already done, deny all traffic first coming from these DMZ servers going to anything on your internal networks, then permit all other traffic. It shouldn't be very CPU intensive, the PIX can easily handle hundreds of ACL's.
Alternatively, in 6.2 you can create object-groups and then define that in an ACL, so it'll at least clean up your config a bit. Create a network object-group for all your inside networks and then you just have one "deny" line in your ACL.
