Did you mean access-list 120, as opposed to access-list 20? If you have a crypto map applied to an interface, and remove the ACL associated with the crypto map, you get the same results as if you deleted an interface-applied ACL without removing the application- IOS assumes the null ACL is a deny any (or encrypt everything), and you will stone up traffic on that interface.
Good real-world lesson- it won't matter in the lab because (I assume) everything is direct console access- but if you're accessing a customer router in-band from its outside interface, remove the crypto map from the interface if you're modifying tunnels, otherwise you'll be calling him/her to reboot it :-) ----- Original Message ----- From: "pat" To: ; Sent: Tuesday, May 21, 2002 12:00 AM Subject: problem with crypto access list !!! > I am trying to set up site to site tunnel between > cisco routers.
