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 :-)
