If the configuration contains conduits to allow inbound traffic to the internal servers, and then you apply an access list to the outside interface, this overrides all of the conduit statements.

You should use either access lists or conduits to permit inbound traffic into the internal networks, but do not use both.

1. No

2. See above.

3. You should convert your conduits into an access-list and apply that access-list to your outside interface.
