Hello.

On an ASA 1120, what is the result of placing on the outside interface, an ACL with a single entry "permit IP any any"?

Thank you.

@jmaxwellUSAF that is unwise and insecure, you are permitting all traffic from the internet (assuming the outside interface is connected to the internet) into the LAN. With a firewall you explictly permit the traffic you want and deny the rest.

Thank you. 

I just wanted to confirm before I confront my boss who did this!
